fix(loop-in-3d): use canonical window.feedBack namespace (post-#537)

The new song:ready loop-applier landed on the legacy window.slopsmith
alias because the branch predated the slopsmith->feedBack rename (#537).
Normalize it to window.feedBack like the rest of core; the alias would
have worked but leaves the lone slopsmith reference in the file.

 ## [Unreleased]
 
 ### Added
-- **3D Drum Highway: bloom glow + adaptive-resolution support — the first slice of visual parity with the guitar highway.** The drum highway now renders through the same post-processing path as `highway_3d`: an `UnrealBloomPass` (strength 0.65, radius 0.5, threshold 0.82 — high, so only emissive/bright surfaces bleed) on a multisampled HalfFloat target with ACES filmic tone mapping, so the white hit-line bar and proximity-lit notes get a real glow instead of a flat emissive tint. **On by default**, with a new **Graphics → "Glow (bloom)"** toggle in the plugin settings (`drum_h3d_bg_bloom`, applies live, no reload); if the vendored postprocessing addons can't load (older self-hosted core), the plugin silently falls back to the direct render path. The plugin also now honors the host's **adaptive render scale** (`bundle.renderScale` — the Quality/"Min res" controls that the guitar highway already respected), multiplying it into the device pixel ratio, and caps DPR at 1.25 when more than one viz instance is live (splitscreen) so two panels don't double the GPU fill cost. Groundwork for the rest of the parity series: an FX-settings scaffold (`FX_DEFAULTS`/`readFxSettings`/`window.drumH3dSetFx`, `drum_h3d_bg_*` localStorage keys) that the sparks/themes/backgrounds PRs extend, plus a first node test suite for the plugin (`plugins/drum_highway_3d/tests/data_layer.test.js` — vm-loaded like the keys plugin's, covering the hit-variant precedence, the Auto-mode steal-guard predicate, and FX defaults; 8 tests, runs in CI via the `plugins/*/tests/*.test.js` glob).
-- **3D Keys Highway: sharp HiDPI rendering, bloom glow, a live combo HUD, and a graphics settings panel — the first slice of visual parity with the guitar highway.** The biggest single fix is resolution: the plugin never called `setPixelRatio`, so on HiDPI/retina displays (and Windows display scaling) it rendered at CSS resolution and was upscaled — soft and aliased. It now multiplies the device pixel ratio (capped at 2, or 1.25 when two viz panels are live in splitscreen) with the host's **adaptive render scale** (`bundle.renderScale`, the Quality/"Min res" controls), exactly like `highway_3d`. On top of that: the same **bloom** post-processing path as the guitar highway (UnrealBloomPass 0.65/0.5/0.82 on a multisampled HalfFloat target + ACES tone mapping — the cyan hit-line, hit flames and the sustain "consume" glow finally bleed light instead of reading flat), **on by default** with a graceful direct-render fallback when the vendored addons can't load. The plugin gains its first **settings panel** (`settings.html`, Settings → graphics category, `"settings"` block in plugin.json) with a live-applying "Glow (bloom)" toggle (`keys3d_bg_bloom`), plus the FX scaffold (`FX_DEFAULTS`/`readFxSettings`/`window.keys3dSetFx`, `keys3d_bg_*` keys) the later parity PRs extend. And the score state the plugin was already tracking is finally visible: a **combo / accuracy / best-streak HUD** overlay (drum-highway pattern), shown only while a MIDI keyboard session is wired so it never renders a frozen 0× combo. Tests: `plugins/keys_highway_3d/tests/fx_settings.test.js` (defaults, localStorage overrides + type coercion, setter persist/dispatch/unknown-key guard; 3 tests alongside the existing 20).
-- **The 3D Drum Highway and 3D Keys Highway are now bundled core plugins** (`plugins/drum_highway_3d/`, `plugins/keys_highway_3d/`), imported from their former standalone repos (`feedBack-plugin-drum-highway-3d`, `feedBack-plugin-keys-highway-3d`, now archived) via `git subtree` so their history is preserved. They join the other in-tree plugins-as-plugins: the loader treats them identically to user-installed ones, both are marked `"bundled": true` in their manifests, and `.gitignore` gains the matching `!plugins/<id>/` exceptions. This puts all three 3D highways (guitar, drums, keys) in one repo ahead of a visual-parity pass that ports the guitar highway's polish (bloom, sparks, themes, reactive backgrounds) to the other two — shared helper code and theme tables can now be reviewed and kept in sync in a single place. The keys plugin's existing node test suite is wired into CI (the JS test step gains a `plugins/*/tests/*.test.js` glob, +20 tests), and `static/tailwind.min.css` is regenerated since the core Tailwind build scans `plugins/**`. One deliberate behavior change ships with the bundling: the drum highway's Auto-mode predicate is **narrowed** (it used to claim any pack with `has_drum_tab` — a pack-level flag — which, now that the plugin ships to everyone and sorts before `highway_3d` in first-match-wins Auto order, would have stolen full-band packs from the guitar highway even on Lead/Bass arrangements; it now claims only drum arrangements, or packs nothing more specific can render). Picking the drum highway manually from the viz picker is unchanged.
-- **The tuner now tracks what tuning your instrument is *actually* in, so it prompts you to retune in BOTH directions — down to a song's tuning, and back up when the next song needs it.** The coverage check used to compare each song against your fixed instrument-profile tuning, so it only ever prompted you *away* from "home" (e.g. E → Drop C#) and stayed silent coming back (Drop C# → E), even though you'd physically retuned. It now reads the host's live **per-instrument working tuning** (`window.feedBack.workingTuning`) — what your selected instrument is currently in — so coverage is measured against your *actual* tuning and fires both ways. When you clear an auto-opened tuner, the tuner publishes that song's tuning as your instrument's live working tuning (`assumed` — an explicit "I tuned / Skip" refines it in a later PR), so the next song is judged against where you now are. **Per-instrument** — your guitar's and bass's tunings are tracked separately (keyed like the selector), so switching instruments uses the right one. Feature-detected: on a host without the working-tuning capability it falls back to the static `/api/settings` tuning (today's behavior). `plugins/tuner/screen.js` (`_playerTuning` reads `workingTuning` keyed by the selected instrument; `_publishWorkingTuning` writes on clear). Builds on the host `workingTuning` foundation (PR 1 of the series) + the instrument→chart routing (PR 2). Tests: `tests/js/tuner_auto_open.test.js` (both-directions coverage via a live Drop-D working tuning; publish-on-clear targets the right instrument slot) — 29 pass.
-- **`.jsonc` support for feedpak data files** (feedpak-spec §8, FEP #3 / PR #13). Hand-edited packs may now use the `.jsonc` extension (JSON with C-style `//` line and `/* */` block comments) for any data file the manifest points at — arrangements, notation sidecars, `drum_tab`, `song_timeline`, `lyrics`, and `keys`. New shared `lib/jsonc.py` provides `parse_jsonc(text)` + `load_json(path)` (auto-detects `.jsonc` by suffix, string-aware so comment-like text inside JSON string values is preserved) and is now used by every reader in `lib/sloppak.py` (six side-file sites) and `scripts/lift_keys_notation.py` (three arrangement / song_timeline read sites). The strip regex mirrors the reference validator in `feedpak-spec/tools/validate.py`. This is an additive (MINOR) change: `.jsonc` is opt-in, so any pack that keeps its data files as `.json` is unaffected and needs no regeneration. Note that a `.jsonc` file containing real comments only loads on a reader that implements §8 — a pre-this-change reader calls bare `json.loads` and fails on the comments rather than ignoring them, so don't hand out `.jsonc` packs to older hosts. Tests: `tests/test_sloppak_jsonc_load.py` (covers all six side-file types, the lift helper, and the string-boundary preservation rule end-to-end).
-- **The highway now loads the part that matches your selected instrument — a bass player gets the Bass arrangement, not the default Lead/guitar chart.** When you open a song without an explicit arrangement, the WebSocket handler (`server.py` `highway_ws`) reads your selected `instrument` from `config.json` (the same file it already reads for your default-arrangement preference) and routes to the matching part: **bass → the Bass arrangement**; guitar — and any unknown/future instrument (drums, keys) — falls through to the existing preference/most-notes default, which already lands on a guitar part. Previously the instrument selector only fed the tuner, so a bass player was handed a guitar chart (and a tune/coverage check then compared a 4-string bass against a 6-string part). An **explicit arrangement request always wins** (a manual arrangement switch is untouched), and a bass player's saved default-arrangement preference is still honored **within** the bass parts (so a preferred `Bass 2` / `Alt. Bass` wins over the canonical Bass), so this only changes the *default* part chosen on load. Server-only — every launch path already flows through the WS, so there's no client change. This is the instrument↔chart-routing piece the working-tuning series leans on (otherwise coverage compares across instruments). Tests: `tests/test_highway_ws_instrument_routing.py` (bass→Bass, bass-honors-pref, bass-no-bass-part→guitar, guitar→default, explicit-wins).
-- **Host "working tuning" — a live, app-wide record of what tuning your instrument is *actually* in right now (foundation; no behavior change yet).** Introduces `window.feedBack.workingTuning`, a host-owned, session-lived state distinct from any one song's tuning and from a soft opt-in default: the offsets + string-count + reference pitch the player's instrument is currently in, plus an `assumed`/`verified` provenance flag. It's **per-instrument** — your guitar's current tuning and your bass's are kept *separately* (keyed like the instrument selector, e.g. `guitar-6` / `bass-4`), so switching instruments surfaces that instrument's own remembered tuning and you only ever deal with the one you've selected. It exists so a retune — or an instrument swap mid-session — is reflected **everywhere** (the highway, the library/song-picker, and plugins like the tuner, Virtuoso, and the minigames) instead of being re-derived per surface or wrongly assumed from a fixed profile. Modeled on the shipped `tuning` capability + the `feedBack.theme` read-API: a **synchronous `get(instrument?)`** (returns the selected instrument's state, defaulting to the seed until known), a `set(state, {provenance, instrument})` mutator (the tuner becomes the sole writer in the next change), `setCurrentInstrument()` for the selector, `resetToDefault()`, and a `working-tuning-changed` event that fires on every change **and once on hydration** (carrying which instrument changed) so a late-mounting consumer is never stuck on stale state. State is **in-memory, seeded from `/api/settings` on boot and reset on restart** — a stale "you're in drop-A" assumption is worse than re-asking. Registered as a separate `working-tuning` **exclusive-owner** capability (tuner = writer, the rest = requesters). This is the foundation (plumbing only — nothing writes to it yet) of the working-tuning series, which fixes the tuner gate only ever prompting *away from* a fixed "home" tuning (never back) and makes the current tuning a first-class signal the whole app shares. Offsets use the same per-string semitone vocabulary as song tunings, so fully custom/extended tunings (e.g. a drop-A 8-string) are first-class. Frontend-only: new `static/capabilities/working-tuning.js`, loaded from `static/index.html` + `static/v3/index.html`.
-- **The v3 Songs grid is now DOM-virtualized — card-node count stays bounded no matter how big the library is or how far you scroll.** The grid used to append every scrolled page and never let go, so a 2000-song library grew the DOM from 24 → 624 → 2001 card nodes as you scrolled (layout/memory cost scaling with depth). It now renders only the **visible window** of cards (± a small overscan); a sizer element sized to the whole library (`ceil(total/cols) × rowH`) gives the scrollbar its full geometry while the grid is absolutely positioned to the first visible row. `state.songs` is a sparse, absolutely-indexed store fetched a page at a time on demand — using the stage-1 **keyset cursor** for contiguous forward scroll (O(page)) and falling back to `OFFSET page=` for jumps/restore/non-keyset providers (collections, remote). Verified bounded (~60 nodes for a 2001-song library while the count still reads "2001 songs"). The **A–Z rail now seeks directly**: `sort_letters` gives a letter's first-row index (cumulative of prior buckets), converted to a scrollTop in O(1) — no more paging through every intervening row (a bounded forward scan covers the rare legacy provider without `sort_letters`). Select-mode selections, accuracy badges, the ⋮ card menu, plugin card actions, scroll-restore (now scrollTop-based, since geometry is stable), and the tree/folder views all survive cards leaving and re-entering the DOM. Plugins that decorate cards get a stable `window.v3Songs.visibleCards()` accessor + a `v3:library-window-rendered` event instead of assuming every card is present (the highway-stutter lesson). Stage 2 of the virtualized-grid project (got-feedback/feedBack#636 item 3), building on the stage-1 keyset data layer below. Frontend-only: `static/v3/songs.js`, `static/v3/v3.css`. Tests: `tests/browser/v3-grid-virtualization.spec.ts` (bounded-DOM invariant across a 2001-song scroll + direct rail jump), updated `tests/js/v3_az_rail.test.js` + `tests/js/v3_songs_scroll.test.js`.
-- **Keyset (cursor) pagination for the library grid — the data layer for an upcoming virtualized grid, and a latent paging bug fixed along the way.** Every library sort now carries a unique `filename` tiebreak, making the order **total** — which fixes a latent bug where rows sharing a sort key (e.g. two songs by the same artist) could be skipped or duplicated across `OFFSET` pages. `GET /api/library` gains an opaque `after` cursor + a `next_cursor` in the response: passing the cursor back fetches the next page with a **WHERE-seek** instead of `OFFSET`, so deep paging is O(page) regardless of depth. The seek is NULL-aware and exactly `OFFSET`-equivalent (verified across artist/title/recent, ascending + descending, including the legacy `dir=desc` shape and NULL sort keys); unknown/compound sorts and bad cursors fall back to `OFFSET`, and only the local provider is handed a cursor (collections/remote page by `OFFSET`). New composite `(artist NOCASE, filename)` / `(title NOCASE, filename)` / `(mtime, filename)` indexes cover the order. This is stage 1 of the virtualized-grid project (got-feedback/feedBack#636 item 3); the DOM-recycling render window builds on it next. Tests: `tests/test_library_keyset.py` (keyset==OFFSET parity, stable tiebreak, dir=desc, NULL keys, cursor fallback).
-- **Smart collections — save a set of library filters as a live, auto-updating source.** A collection is a saved `/api/library` query (e.g. "Drop-D tunings", "sloppak only", "recently added") that stays live: it's registered as a **library provider**, so it shows up in the v3 Songs source picker and inherits the whole grid UI — paging, stats, the A–Z rail, art — for free, with **no new screen**. Storage reuses the playlist subsystem (a `playlists.rules` JSON blob = a smart collection; membership is the live filter result, not stored songs, and collections are excluded from the manual-playlist list + read-only to playlist mutations). New `GET`/`POST`/`PUT`/`DELETE /api/collections`; a per-collection `SmartCollectionProvider` delegates `query_page`/`query_stats`/`query_artists` to the local DB with the stored rules applied; providers are re-registered from a boot scan so collections survive a restart. Rules mirror the raw `/api/library` query params (unknown keys dropped, never 500). Frontend: a "＋ Save as collection" action in the v3 filter drawer (shown when filters are active) names the current filter set and switches to it. The charrette's "the homelab primitive FeedBack was missing" pick (got-feedback/feedBack#636 item 2); richer rule fields (accuracy, genre, difficulty) follow as the metadata work lands. Tests: `tests/test_collections_api.py`, `tests/js/v3_collections.test.js`.
-- **The settings backup now includes your library database + custom art — your scores, favorites, playlists, and play history are no longer the one thing a backup can't save.** `GET /api/settings/export` gains an additive `core_server_files` section carrying a **consistent snapshot of `web_library.db`** (taken via the SQLite online-backup API, so it's a complete single file even while the server is running) plus any custom **playlist covers** and **avatar** (`CONFIG_DIR/playlist_covers/`, `CONFIG_DIR/avatars/`). On `POST /api/settings/import` the database is **staged** to `web_library.db.restore` rather than written over the live, open DB; it's swapped in at the next startup (`_apply_pending_db_restore`, before the connection opens), which also clears the old WAL sidecars so a stale `-wal` can't be replayed onto the restored file — the import response sets `restart_required: true` and warns accordingly. Custom art is written immediately. The bundle stays backward-compatible (older servers ignore the new section). Came out of the library design charrette (dev-ops lens's top "protect irreplaceable data" pick, got-feedback/feedBack#636). _Known gap:_ custom uploaded **song** art is still commingled with the rebuildable thumbnail cache in `art_cache/`, so it isn't bundled yet (a tracked follow-up). Tests: `tests/test_settings_export_library_db.py` (snapshot consistency, staged-not-live restore, sidecar clearing, traversal rejection, full round-trip).
-- **A persisted wishlist — keep a list of songs you want but don't own yet.** New `wanted` table + `GET`/`POST`/`DELETE /api/wanted` give FeedBack the *arr-style "Wanted/Monitored" primitive it was missing: an entry is a *not-owned* song (artist/title/source/source_ref/note), so it lives in its own table rather than the playlist subsystem (which references owned local files). The API is idempotent on identity (case-insensitive artist+title, plus source+source_ref), so a producer — the `find_more` ownership-diff, or a manual add — can re-post without duplicating. Newest-first. Backend primitive for the charrette's wishlist finding (got-feedback/feedBack#636 item 4); the consuming UI lives in the producing plugin. Tests: `tests/test_wanted_api.py`.
-- **Practice-aware library home — a "Repertoire" meter + a "Keep practicing" shelf on the v3 Songs page.** The library opened cold into a flat sorted grid; now the unfiltered grid front door leads with two practice-aware surfaces built entirely from data already on hand (no new endpoints or stored state). A **Repertoire meter** shows how much of your library you can actually play — *"Repertoire: 12 of 80 songs · 7 in progress"* with a progress bar — counting songs at or above the same mastery threshold the green accuracy badge uses (≥ 90% best accuracy) over the unfiltered library total. A **"Keep practicing" shelf** is a horizontal row of your recently-played-but-not-yet-mastered songs (newest first, click to play) — the practice-accuracy-driven "continue" rail a media server can't do. Both reuse `/api/stats/best` (already loaded for the card badges) + `/api/stats/recent`; they show **only** on the grid view when you aren't searching/filtering/selecting, refresh after a song is scored, and collapse to nothing on an empty library. Soft-gamification only — descriptive encouragement (goal-gradient / endowed-progress), never content-gating, decay, or nagging. Frontend-only: `static/v3/songs.js` (`renderLibraryHome`/`_repertoireCounts`), `static/v3/v3.css`. Came out of the library design charrette (the UX + gamification lenses' top pick). Tests: `tests/js/v3_keep_practicing.test.js`.
-- **A–Z fast-scroll rail on the v3 Songs grid.** A vertical letter rail (Plex/Radarr/iOS-contacts pattern) pinned to the right edge next to the scrollbar lets you jump the library to a starting letter — tap a letter, drag to scrub with a live letter bubble, or arrow-key between letters. It shows **only** for the grid view + alphabetical (artist/title) sorts, and only offers letters actually present in the current sort **and filter set**, so a tap always lands on a real card (absent letters are dimmed + non-interactive). Because the grid is forward-only, server-paged infinite scroll, a jump pages through to the target card and scrolls to it (a newer jump supersedes an in-flight one); a keyset-seek + virtualized window is the noted scaling follow-up for very large libraries. Backend: `/api/library/stats` now accepts `sort` and returns an additive `sort_letters` map (songs-per-first-letter of the active sort column — artist or title), filter-synced; the legacy `letters` (distinct-artist) field is unchanged for the dashboard + classic tree. Frontend: `static/v3/songs.js` (`refreshRail`/`jumpToLetter`, cards tagged with `data-letter`), `static/v3/v3.css` (`.v3-azrail`). The classic (v2) tree already had letter selection; this brings the new grid to parity. Tests: `tests/test_library_filters.py` (sort_letters artist/title + song-vs-artist counting), `tests/test_library_providers.py` (sort forwarded to providers), `tests/js/v3_az_rail.test.js`.
-- **Playlists get content-dependent covers + custom art.** Playlist cards were a tiny `🎵` emoji on an empty square. Now a playlist's cover reflects its contents: **empty → the icon**, **a few songs → the first song's album art**, **4+ songs → a 2×2 art mosaic**. You can also **upload a custom cover** (a "Cover" button in the playlist detail view → image picker; "Remove cover" reverts to the content view). `MetadataDB.list_playlists()` now returns each playlist's first few song `art_urls`; `GET /api/playlists` and `GET /api/playlists/{id}` add `cover_url` when a custom cover exists. New routes `POST` / `GET` / `DELETE /api/playlists/{id}/cover` store a small PNG thumbnail under `CONFIG_DIR/playlist_covers/` (PIL-converted, like song-art upload); the cover is removed with the playlist. Frontend: `playlistCoverHtml(p)` in `static/v3/playlists.js`. Tests: `tests/test_playlists_api.py` (art_urls + cover roundtrip / reject-non-image / delete-cleanup), `tests/js/v3_playlist_cover.test.js`.
-- **v3 Songs: "Add to playlist" is now on each song's ⋮ "More" menu.** Previously a song could only be added to a playlist through select-mode (the checkbox → batch bar). The per-card overflow menu now has an **Add to playlist** row that targets that one song, reusing the same picker (choose a listed number or type a new name to create it). The select-mode batch flow and the single-song menu now share one extracted `addFilenamesToPlaylist(filenames)` helper in `static/v3/songs.js` (both grid and tree rows, since they share `openCardMenu`). Tests: `tests/js/v3_add_to_playlist_menu.test.js`.
-- **Resume where you left off — leaving a song now snapshots your place so an exit is recoverable, not a restart-from-zero.** Exiting the player (`showScreen()` teardown, before audio unload) writes `{song, arrangement, position, speed}` to `localStorage` (`feedBack.resumeSession`), and a non-blocking **"Resume practice"** pill offers it back on the next non-player screen (and on the next app launch). Clicking Resume re-enters the song, restores the arrangement + playback speed, and seeks to the saved position via the existing `_audioSeek` funnel; `playSong()` gains a `{ resume: {position, speed} }` option that arms a `song:ready`-consumed restore instead of the normal autostart, so the two never fight over playback. The snapshot is deliberately conservative — ignored for a song you barely started (< 3s) or had basically finished (within 5s of the end), cleared on natural song-end and once consumed, and expired after 24h. The pill is self-contained (inline-styled, body-appended, works identically in the classic and v3 shells with no Tailwind rebuild), never blocks, and a dismiss forgets the current snapshot for the session. This pairs with the Escape focus fix: now that Escape reliably leaves regardless of focus, an *accidental* exit is one tap to undo. Public surface: `window.resumeLastSession()` / `window.feedBack.resumeLastSession`. (The broader nav-state work — returning to a song after wandering into Settings → Tone Builder — is a separate, larger track; this lands the player-session slice.) Tests: `tests/browser/resume-session.spec.ts` (snapshot guards, staleness, pill show/hide/dismiss, resume consumption).
-- **Optional "Ask before leaving a song" confirm (Gameplay tab, default OFF).** A new client-only toggle (`confirmExitSong` in `localStorage`, in the v3 Gameplay settings + the Gameplay "Reset" set) for players who want a guard against an accidental exit. **Off by default — Escape leaves instantly, zero change for everyone else.** When on, a *user-initiated* exit (the player-scope Escape shortcut, or the player's ✕) opens a small true-modal confirm instead of leaving; auto-exit on song-end and a results screen's own Close are unaffected (they call `closeCurrentSong()` directly, which stays the unguarded actual-exit). The confirm honors the team's refined asks: **opening it pauses the song** (so it isn't running or being scored behind the prompt) and **Stay resumes exactly what was paused**; **Escape = Stay** — the dialog's capture-phase handler *dismisses* it (now consistent with every other modal and the generic `_confirmDialog`'s Esc=cancel), so a second Escape returns you to the (resumed) song rather than leaving; **Space/Enter (or click) Leave** by natively activating the default-focused "Leave" button ("just get me out"). Pause/resume run through the canonical `togglePlay()` path (HTML5 + `_juceMode`), guarded so a count-in, an already-paused song, or a teardown/seek/end behind the modal can't mis-resume. It's a real modal (`role="dialog" aria-modal="true"` / `.feedBack-modal`) with **Tab trapped inside it** and a **backdrop click that also Stays**, so the Escape/Space focus carve-outs treat it as a trap and don't fire player-back / play-pause behind it. The player Escape shortcut and the v3 ✕ route through a shared `window.requestExitSong()` gate (the ✕ also becomes origin-aware, matching Escape). Tests: `tests/browser/exit-confirm.spec.ts` (default-off instant exit, confirm-on opens + stays, second-Escape stays, backdrop stays, Stay/Leave, Enter-leaves); the audio pause/resume is verified manually on web + desktop (the mock song has no backing track).
-- **Folder Library — a bundled core plugin (`plugins/folder_library/`) that browses the DLC library by its on-disk folder tree.** Surfaces top-level folders → subfolders → songs (root-level songs land in `(Unsorted)`), with in-app folder management (create / rename / delete nested folders), song moves via dialog or drag-and-drop, and sort/filter that mirrors the host library's filter state. Wired into both the classic (v2) library toolbar and the v3 Songs page as a third **Folders** view alongside grid/tree; the plugin's `screen.js` is loaded once by the host and reused (idempotent IIFEs). Supersedes the former standalone "Folder Organizer" community plugin (removed from the README list). Backend (`routes.py`) registers `/api/plugins/folder_library/{tree,folder/create,folder/rename,folder/delete,song/move}`; **all filesystem mutations are confined to `DLC_DIR` and validated against path traversal** (per-segment name validation plus a resolved-containment check on `song/move`), and folder deletion relocates every song — de-duplicating colliding names — so a name clash never destroys a song. A two-level cache keeps re-opening folders fast. Tests: `tests/plugins/folder_library/test_routes.py` (path-safety helpers + move-traversal and delete-no-data-loss end-to-end).
-- **Full-screen (immersive) plugin screens — opt-in via `"fullscreen": true` in `plugin.json`.** DAW-style plugin UIs (e.g. a practice studio) need the whole viewport, not a scrolling content page below the topbar — embedded in the v3 shell they get cut off at the bottom with dead space up top. A plugin can now declare a top-level `"fullscreen": true`; `plugins/__init__.py` surfaces it as the `fullscreen` boolean on `/api/plugins` (mirroring the `settings_category` plumbing). When such a plugin's screen is active, `static/v3/shell.js` toggles `html.fb-immersive` from `syncActive()` (so it tracks every navigation incl. deep-link), and `static/v3/v3.css` hides the topbar, collapses the sidebar to a functional **icon rail** (kept reachable — Escape is bound only on player/settings scopes, so a fully-hidden sidebar would trap the user), and lets the active plugin screen fill `#v3-main`. Mirrors the existing `ss-follower-pre` chrome-hide pattern. Additive + opt-in: plugins without the flag are unaffected. Tests: `tests/test_plugins.py::test_fullscreen_flag_parsed_from_manifest`.
-- **Achievements wall sync — background drain worker (epic PR3, client side).** The bundled `achievements` plugin gains a dead-letter sync worker that POSTs queued Feat unlocks (and removals) to the hosted **feedback-achievements** wall service (separate repo). Idle unless a wall URL is configured (`FEEDBACK_ACHIEVEMENTS_WALL_URL`); uses `requests` with the baked-in client-token header, mirroring `lib/lyrics_transcribe`'s outbound pattern (explicit timeout, no raise on non-2xx). **Dead-letter, never drop** (pure `engine.drain_decision`): network error / `429` / `5xx` → keep `pending` (retry); other `4xx` → `dead_letter` (diagnosable, replayable); `2xx` → delete on server ack. A row leaves the queue only on ack or a user opt-out. `remove-me` now enqueues a wall removal keyed by the reused `player_hash`. Verified by an end-to-end staging round-trip (earn a Feat → drains onto the wall with name + short hash → `remove-me` → wall empties) with **no IP** in tables or access logs. Tests: `tests/plugins/achievements/test_sync.py` (decision table + ack/retry/dead-letter retention + four-field payload on the wire). The hosted service itself (FastAPI + SQLite-on-disk, Feats-only, hidden-until-first-global-unlock, profanity filter, in-memory rate limit, Render blueprint, migration tool) lives in the new `feedback-achievements` repo.
-- **Achievements wall — opt-in, privacy controls & data-minimization gate (epic PR2).** Sharing earned **Feats** on the (forthcoming) public wall is strictly opt-in. A new **onboarding step** (`static/v3/profile.js`, inserted after song-directory / before instrument paths — the wizard is now five steps) presents a plain-language card: it publishes only your display name and the Feats you earn, never songs/skills/scores, and is **off by default**. The bundled plugin's Settings panel (`plugins/achievements/settings.html`, mounted under the **System** tab via `settings.category`) carries the same toggle plus a **"Remove me from the wall"** button (`POST /api/plugins/achievements/remove-me` — wipes local synced state offline + enqueues a wall removal). Core adds `achievements_enabled` (bool, default `false`) to `_default_settings()` + the `/api/settings` validation block + `_RESETTABLE_SETTINGS_KEYS` in `server.py`, mirrored to `localStorage` in `app.js loadSettings()`. **Data-minimization contract (binding, code-enforced):** every outbound payload is built by a single explicit-dict serializer (`engine.build_wall_payload`, never `dict(row)`/`**model`) whose key-set is **exactly** `{display_name, player_hash, achievement_id, unlocked_at}` with `achievement_id` always a **Feat** id — a unit test asserts the four-field set and goes red on a fifth. Enqueue is doubly gated: it happens only when opted-in **and** a profile identity (name + the reused `player_hash`) exists; **competency unlocks never enqueue** (integration law). Tests: `tests/plugins/achievements/test_datamin.py` (key-set, opt-out/identity/competency gating) + `tests/test_settings_api.py` (flag persists/validates/resettable).
-- **Achievements & Feats of Power — local engine + tabbed Profile (epic PR1).** The Profile screen (`static/v3/profile.js`) becomes **tabbed** exactly like the v3 Settings page (`.fb-tabbar` / `.fb-tab[data-tab]` / `.fb-tabpanel[data-tab]`, active-tab persisted in `localStorage 'v3-profile-tab'`): a **Profile** (main) tab carrying the existing header + best-scores cards plus a new **Feats of Power** trophy shelf mount (`#v3-profile-feats-slot`, earned-only / hidden-until-earned), and an **Achievements** tab with a plugin mount (`#v3-profile-achievements-mount`) + `[data-empty-for]` empty note. Core dispatches a new **`v3:profile-rendered`** event after every render (mirrors `v3:settings-rendered`) so the plugin re-injects on each profile entry. A new bundled **`plugins/achievements/`** plugin owns the engine: SQLite under `<config_dir>/achievements/achievements.db` (`unlocks` / `counters` / `comp_ledger` / `sync_queue`), pure threshold/criterion math in the testable sibling `engine.py` (P-V), and routes under `/api/plugins/achievements/` (`activity`, `report-unlock`, `report-criterion`, `catalog`, `earned`, `feats`, `remove-me`). **Two surfaces, one engine, structurally separated (integration law):** **Feats** (activity/volume — Note Hunter, Marathon, Untouchable, Road Warrior, Time Served, Encore, two 🥚 secrets) read activity counters only, evaluated from a batched `song:ended` activity POST (notes only when **notedetect** is present — graceful degradation, no fake progress); **competency Achievements** (baseline: First Steps / Ascendant / Steady Hands / Renaissance + per-instrument Apprentice·Journeyman·Master / Personal Best / Challenger) are evaluated from **progression events only** and never re-derived from activity. The Achievements catalogue is always shown (locked = greyed), grouped by a secondary pill row over the **real progression paths** (Global / Guitar / Bass / Drums / Keys — auto-extends to new paths) with a per-category "X / Y earned" badge, defaulting to the player's primary path. Source plugins contribute their own competency defs and report unlocks through a versioned **`window.feedBack.achievements`** API (`register`/`registerAll`/`unlock`/`progress`), load-order-safe via the `window.__feedBackAchievementsPending` queue + an `achievements:ready` event (minigames pending-queue pattern); an absent source contributes nothing (no dead greyed rows). Opt-in publishing to a hosted Feats wall, the Settings privacy toggle, and the data-minimization gate land in epic PR2/PR3. Tests: `tests/plugins/achievements/test_engine.py` + `test_routes.py` (incl. the integration-law assertion that a competency unlock never reaches the Feats shelf).
-- **v3 settings page redesigned as a tabbed, card-row layout.** The single long scrolling settings screen becomes a horizontal tab bar (Gameplay / Audio / Graphics / Keybinds / Progression / Mic / Plugins / System) over card rows — each a leading icon + title + description with the control (toggle/dropdown/slider) on the right, plus a per-category "Reset" action. The markup lives in `static/v3/index.html` (so existing element ids keep hydrating through the unchanged `app.js` `loadSettings()`/`persistSetting()` path); a new `static/v3/settings.js` owns tab switching + active-tab persistence (`localStorage 'v3-settings-tab'`), the per-category reset, and a read-only **Keybinds** reference built from the live shortcut registry (`window.getAllShortcuts()`); styling is plain CSS in `static/v3/v3.css` (no Tailwind rebuild). **Plugins choose their settings tab** via a new optional `settings.category` field in `plugin.json` (`plugins/__init__.py` surfaces it as `settings_category`; `app.js` mounts each plugin's `<details>` panel into `#plugin-settings-<category>`, falling back to the generic Plugins tab) — `highway_3d` ships `category: "graphics"`; the out-of-repo notedetect/progression plugins should declare `"mic"` / `"progression"`. **New gameplay settings:** **Countdown before song** (a four-beat count-in before playback, wired end-to-end via the existing count-in engine + the song-start autostart path; key `countdown_before_song`, default off); **Miss penalty** (`miss_penalty`) and **Fail behavior** (`fail_behavior`) are persisted now but not yet consumed by scoring (shown with a "Not yet active" badge). "Note highway speed" surfaces the existing `master_difficulty` and stays in sync with the player-popover difficulty slider. New `POST /api/settings/reset` clears chosen keys back to defaults. Tests: `tests/test_settings_api.py` (new keys + reset), `tests/test_plugins.py::test_settings_category_parsed_from_manifest`, `tests/browser/settings-tabbed.spec.ts`.
-- **Full-mix audio exposed alongside stems for the stem mixer's auto-switch.** `lib/sloppak.py::load_song` now parses the optional manifest `original_audio:` key (the single pre-separation mixdown, e.g. `original/full.ogg`) into a new `LoadedSloppak.original_audio` field, with the same path-traversal guard and permissive "missing → disabled" posture as the `drum_tab` loader. The highway WS `song_info` frame additively carries three new fields next to `stems`: `original_audio_url` (served by the existing `/api/sloppak/{filename}/file/{rel_path}` endpoint, `None` when the pack ships stems only), `has_original_audio`, and `has_stems` (mirroring the `has_drum_tab`/`has_keys` flag convention). The stems plugin consumes `original_audio_url` to play the untouched single file while every stem slider is at unity and switch to the separate stems the moment one drops below 100%. **Migration notes:** the `song_info` message shape is a stable contract — these are purely additive; all existing fields are unchanged. `audio_url` still points at stem[0] when stems exist (it is only the degraded native fallback); the one behavioural change is that a stem-less, full-mix-only sloppak now sets `audio_url` to the full mix instead of emitting `audio_error`, so it plays natively.
 - **Autoplay & auto-exit — a global "click it, it plays; finish, you're back at the menu" option (default ON).** New single Settings toggle (`autoplayExit` in `localStorage`, surfaced in both the v3 and classic settings screens; absence of the key = enabled) that closes the friction at both ends of the play loop. **Autoplay:** `playSong()` previously loaded a chart paused, requiring a Play press; a one-shot flag armed per fresh load is now consumed by the next `song:ready` (highway.js) to auto-start via the existing `togglePlay()` path (HTML5 + `_juceMode` + count-in). Arrangement switches / seeks reuse the same `song:ready` event but never arm the flag, so they don't auto-restart. **Auto-exit:** on `song:ended`, core returns to the launching menu after a short grace delay — unless a visible full-screen results/dialog overlay is on top (detected via `[role=dialog][aria-modal]` / `.fixed.inset-0` with a `getClientRects()` visibility test that works for `position:fixed`), in which case the return is deferred so that score screen's own Close button (calling `window.closeCurrentSong()`) drives the exit. A plugin can also defer explicitly via the new `window.feedBack.holdAutoExit()` (called synchronously from its own `song:ended` handler — core's listener runs first). Both paths mean **no external plugin PR is required** for a results screen to be respected. **Context-aware destination:** the player's remembered origin (`_playerOriginScreen`) now honours any real launch screen instead of clamping to library/home/favorites, and a one-shot `window.feedBack.setReturnScreen(id)` override lets the lessons catalog (`static/v3/lessons.js`) send a finished lesson back to the lessons screen — not the song library — even though the external tutorials plugin owns the `playSong` call. Also exposes a read-only `window.feedBack.autoplayExit` getter for plugins. Songs and lessons share the same `playSong` → highway path, so both inherit the behaviour. Core-only (`static/app.js`, `static/v3/lessons.js`, both `index.html`s); the end-of-song score screen itself remains a plugin. Optional polish (not required — the overlay heuristic already covers it): external scoring/note-detection plugins (e.g. SlopScale) may call `holdAutoExit()` + `closeCurrentSong()` for an exact, heuristic-free handoff.
 - **"Song Editor" promoted to a first-class v3 sidebar item.** The editor
   plugin (`id: editor`) now gets its own dedicated sidebar entry — under the

 - **v3 library: exact artist/album filters + scroll/page-depth restore** (feedBack#857). The v3 Songs toolbar gains Artist and Album dropdowns (Album populates from the selected artist and stays disabled until one is chosen), backed by new exact, case-insensitive (`COLLATE NOCASE`) `artist` / `album` query params threaded through `MetadataDB._build_where` → `query_page` / `query_artists` / `query_stats` and the `/api/library`, `/api/library/artists`, `/api/library/stats` endpoints (the free-text `q` search stays fuzzy and composes with the exact filters). The artist/album catalog is fetched independently of the active artist/album selection so the dropdowns always list the full set for the current provider/search. The toolbar is now sticky so filter controls stay reachable when browsing deep libraries, and returning from the player restores the previous scroll position **and** the loaded infinite-scroll page depth via a `sessionStorage` snapshot keyed by a filter/sort/view state hash (invalidated whenever those change, so a filter change still resets to the top). Tests: `tests/test_library_filters.py` (backend artist/album filters), `tests/js/v3_songs_scroll.test.js` (state-hash + snapshot helpers).
 
 ### Fixed
-- **Tuner auto-open is now opt-in and persists instead of flashing open-then-shut.** When you entered a song (or switched arrangement) whose tuning differed from the last, the tuner auto-opened and — for some testers — vanished ~1s later (reported macOS+Windows, 0.3.0). Root cause: the tuner closes itself on `song:play` (`plugins/tuner/utils/ui.js` — you don't tune while playing), so a **song switch** fired autoplay → `song:play` → the just-auto-opened tuner closed; an **arrangement switch** (which never arms autoplay) had no `song:play`, so it stayed open — exactly why two testers saw opposite behaviour (it wasn't the mic). Now: (1) the feature is a **new opt-in setting** ("Auto-open on tuning change", in the tuner's Settings panel, persisted as `autoOpenOnTuningChange`, **default OFF**); (2) an **auto**-opened tuner *persists* — it ignores the autoplay `song:play`, stray outside-clicks, and same-screen re-emits, closing only via the new in-panel **`×`** / **"Skip"** buttons or when you leave the song. A *manually* opened tuner keeps its classic click-away / play-to-close behaviour. The panel previously had no in-box close at all; this adds one (`×` + contextual Skip). All in the tuner plugin (`routes.py` config, `screen.js` gate + persist, `utils/ui.js` buttons + `song:play` guard, `settings.html` toggle) — **no core `app.js` changes**. Tests: `tests/js/tuner_auto_open.test.js` (opt-in gate, `{ auto: true }` persist mode, play/click-proofing). **Default (opt-in vs opt-out) is teed up for Byron to decide — flip one boolean.**
-- **Tuner auto-open is now tuning-coverage-aware — extended-range players aren't nagged for songs their instrument already covers.** With the opt-in auto-open on, it now prompts only when your **current physical tuning** (from your instrument selection in Settings) doesn't already cover the song. FeedBack is tune-to-song — the highway draws tab in the song's tuning — so the check aligns the song's open-string tuning string-for-string against your instrument: an **8-string F♯-standard** player gets **no** prompt for a 6- or 7-string standard song (its top strings already match those tunings), while a song needing an open string you don't have (e.g. a **Drop-A 7-string**, whose low A isn't an open string on an F♯ 8-string) **still** prompts. A whole-instrument reference difference also prompts — A440 vs A432, or an octave-down `centOffset` (which the auto-open now accounts for; it was previously ignored). The player's instrument is read from core **`/api/settings`** (the v3 instrument selector — a stable physical reference, not the tuner's song-tracking selection); when nothing's declared or the lookup is unavailable it falls back to a conservative prompt, so a real retune is never silently skipped. **v3-only** (the instrument selector is v3). All in the tuner plugin (`plugins/tuner/screen.js`) — **no core changes**. Tests: `tests/js/tuner_auto_open.test.js` (covered vs uncovered, the Drop-A case, reference-pitch mismatch, contiguous alignment). _Follow-up (E1.6): a passive "different tuning" badge cue that names the string(s) to retune, plus the splitscreen / no-usable-input guards._
-- **The tuner badge now passively flags when a song needs a different tuning — and names the retune.** Building on the coverage check: when you enter a song your current instrument doesn't cover, the topbar tuner badge gets an amber ring and a tooltip that **names the change** — e.g. *"retune B→A"* for a Drop-A song on an F♯ 8-string, or *"the reference pitch"* for an A440-vs-A432 mismatch. It's purely **advisory** (it never auto-opens the panel — tap the badge to tune), recomputed on `song:ready` and cleared when a new song loads or you leave the player. The retune diff comes from the tuner plugin's coverage report (`window._tunerAutoOpen.coverageReport` → `{ covered, retune: [{ from, to }], reference, cantCover }`); the cue is CSS-free (an inline ring + native tooltip — no Tailwind rebuild) and no-ops when the tuner plugin isn't installed. **v3-only.** Touches `static/v3/badges.js` (the cue) + `plugins/tuner/screen.js` (the report). Tests: `tests/js/tuner_auto_open.test.js` (the report names the strings; reference mismatch; the badge wiring). _(The splitscreen-suppress and no-usable-input guards move to the playback-gate stage, where they matter for its no-trap rule.)_
-- **Tuner auto-open can now gate playback until you've tuned — the "tune before you play" model — via a new core `holdAutoplay()` hook.** With the opt-in auto-open on, when a song needs a retune the tuner opens and **playback waits** for your choice — **Skip** (you've tuned → play, and record the song's tuning as your instrument's current working tuning), **Back to library** / **Esc** (leave the song; a gated retune is never a one-way trap), or press **Play** (always wins). For an auto-open the in-panel **×** is dropped — Skip / Back to library / Esc are its dismiss surface. Previously the song played with the tuner overlaid; now it holds — which also definitively kills the original flash, since autoplay's `song:play` can't fire while playback is held. Implemented as a small **core hook** `window.feedBack.holdAutoplay()` (mirrors the existing `holdAutoExit()`): a plugin claims it **synchronously on `song:loading`** (so it beats the `song:ready` autostart), and `release()` — or a **12-second fail-open backstop** — runs the deferred start. **Generation-guarded** (a new song invalidates a stale hold) and **fail-open** (a wedged or crashed plugin can never permanently strand a song); **manual Play always wins** (it doesn't flow through the autostart path). The tuner claims the gate only when the feature is on, and **releases it the instant** it decides not to open (song already covered / tuning unchanged) or when you Skip. Touches core `static/app.js` (the hook + an autostart refactor) and the tuner plugin (`plugins/tuner/screen.js` — the claim/release; `plugins/tuner/utils/ui.js` — the Skip / Back-to-library buttons, × dropped on auto-open); the hook is generic and shell-agnostic (a test asserts `app.js` still doesn't reference the tuner's internals). Tests: `tests/js/tuner_auto_open.test.js` (claim on `song:loading`, release on dismiss, feature-off no-claim, the core hook + fail-open backstop, the Skip / Back-to-library / Esc escape-hatch) + a `speed_reset.test.js` stub. ⚠️ **Needs a manual smoke-test before shipping** — this is a core playback change; verify on desktop that the tuner mic doesn't contend with note_detect's scoring input (ASIO/exclusive mode), per the design charrette.
-- **v3 player: opening another rail popover now closes the Section Practice popover (no more two stacked popovers).** Opening the **Practice** pill's popover and then clicking a different player-rail icon (e.g. **Plugins**) left the Practice popover open underneath the new one — looked broken (reported on macOS, 0.3.0 / 2026-06-28). The rail icons call `e.stopPropagation()` in their click handler (`static/v3/player-chrome.js`), which killed bubbling before it reached the Practice popover's outside-click dismiss bound on `document`. The dismiss (`_installSectionPracticeDismiss` in `static/app.js`) now binds in the **capture phase**, which runs before the target's handler so a descendant's `stopPropagation()` can't swallow it — mirroring how the audio-mixer popover already dismisses. Esc handling stays bubble-phase (the player's Escape-to-exit ordering is unchanged). v2 shares `app.js` and is only hardened (no rail `stopPropagation` there). Tests: `tests/js/section_practice_dismiss.test.js`.
-- **v3 UI no longer lets you accidentally text-select the chrome.** Dragging or double-clicking across the interface used to marquee-highlight buttons, labels, the sidebar, the transport, and the note-highway HUD — which looks broken (reported on Mac + Windows). The v3 shell now defaults to `user-select: none` on `html` (`static/v3/v3.css`), then opts *content* back in — so chrome is non-selectable but the text you actually copy still works. Decided by a 4-lens panel (UX / accessibility / dev-ops / plugin-ecosystem); the guardrails are deliberate: **form fields are always re-enabled** (never break the caret / IME — no `* { user-select:none }`, which trips a WebKit input bug); **plugin screens (`.screen[id^="plugin-"]`) stay selectable by default** so a plugin's copyable text (lyrics, chord names, results) — including community plugins that don't know about this — isn't silently locked; and **core read-only content opts back in by container** via a new hand-authored **`.fb-selectable`** class — applied to the whole **Settings** panel (paths, device names, version, diagnostics, About — answering "is settings still copyable?": yes), the **now-playing song metadata** (with `pointer-events` re-enabled so the HUD text is actually reachable), and the focused **modals / dialogs / toasts / scan banner** that carry copyable errors, IDs, paths, and file names. It's cosmetic only (it protects nothing) and never used to lock copy-worthy text — errors, IDs, paths, versions, and metadata stay selectable per WCAG 2.2 (copy-paste as a permitted mechanism). Dense card lists (library grid, dashboard, profile) stay non-selectable by design — making them selectable would reintroduce the marquee-mess across cards. **v3-only** (v2 unchanged); plain CSS, no Tailwind rebuild; no desktop changes (standard OS-framed window). Plugin authors: `.fb-selectable` is documented in `CLAUDE.md` for re-enabling copyable content rendered outside a plugin screen. Tests: `tests/js/v3_user_select_policy.test.js`.
-- **Input-setup wizard no longer collapses an audio device's driver-type variants into one entry.** On Windows the desktop engine enumerates the same interface once per host API (ASIO / Windows Audio / DirectSound), and the wizard's audio picker (`plugins/input_setup/screen.js`) de-duped the source list by display **label** — so the variants (which share a name) collapsed to a single choice, silently keeping whichever sorted first (often *not* the low-latency ASIO one the player wants). The audio-input capability already collapses true duplicates by `logicalSourceKey` (`_visibleInputSources` in `static/capabilities/audio-session.js`), and the variants each have a **distinct** key, so the wizard's extra label-collapse was redundant for real dupes and destructive for these — it also could drop the variant that was actually `selected`. Removed it; the picker now lists every selectable input. Pairs with feedBack-desktop's change to label each source with its driver type (e.g. "Focusrite (ASIO)") so the now-distinct entries are legible.
-- **3D Highway FPS counter no longer hides behind the v3 "Up Next" pill.** The on-highway FPS readout (Settings → Graphics → 3D Highway → Show FPS counter) is pinned to the top-right of the highway overlay — the same corner the v3 player chrome stacks its persistent **Up Next** pill and live-performance HUD into, on a higher layer that paints over the canvas. So the readout sat *behind* that chrome and couldn't be read — precisely when a tester had turned it on to judge performance (it also made the separate "Up Next won't turn off" complaint worse, since the default-on pill covered the counter regardless). The counter now stays top-right but drops just **below** whichever of that chrome is showing: `highway_3d`'s `screen.js` measures the lowest visible top-right v3 HUD element (`#v3-upnext` / `#v3-live-performance-hud` / `#hud-time`) and floors the FPS box's Y beneath it. Element refs are resolved once and cached (no per-frame `querySelector`, per the plugin perf rules) and only consulted while the counter is actually drawn; gated on `window.feedBack.uiVersion === 'v3'` so the classic (v2) UI is byte-for-byte unaffected. `plugins/highway_3d/plugin.json` version → `3.30.1` (cache-buster). (For reading raw perf numbers unobstructed, the core perf HUD — `localStorage.highwayPerfHud='1'` — still renders above all chrome and additionally shows the adaptive render-scale.)
-- **3D Highway fret-number row no longer clips off the bottom edge when the camera zooms in on a centred span.** The heat-coloured fret-number row is drawn as a band *below* the board (`sY(lowest) − S_GAP*1.4`), but the camera's self-correcting framing only anchors the board **centre** to the lower third of the screen — it reserved no headroom for that row. So a tight zoom on a centred active span (worst around mid-neck; fine when the span sits at either end of the neck, which is why testers saw it "only when centered" and "not every song") dropped the numbers past the bottom edge. Tilt can't fix it there (it would only trade a bottom clip for a top clip), so `camUpdate()` now **dollies the camera back just enough to bring the row back into frame**: it projects the row band with the final camera and, when it falls below a safe NDC line (`FRET_ROW_FIT_NDC_MIN`), raises a capped, hysteretic `_fretRowFitBoost` applied to the `curDist` lerp target (the span-driven zoom still owns zooming *in*). The boost rises promptly (proportional to the deficit), relaxes lazily past a deadband, and is capped (`FRET_ROW_FIT_BOOST_MAX`, +60%) so the zoom can't pop or hunt; it cooperates with the tilt loop (pull-back shrinks the scene, tilt keeps the centre anchored) and yields entirely to the Camera Director free-cam. Surgical: passages where the row is already visible never trigger it, so framing is unchanged everywhere it already worked. `plugins/highway_3d/plugin.json` version → `3.30.2` (cache-buster). Tests: `tests/js/highway_3d_camera_framing.test.js` (guard constants, the boosted `curDist` lerp, the projected-row hysteresis, free-cam yield).
-- **v3 Songs grid now refreshes after a Settings rescan / DLC-folder change — no app restart needed.** On a fresh install, pointing at a DLC folder in Settings and running a scan left the Songs section empty until a restart (the scan *did* populate the library — `_background_scan` re-reads `config.json` fresh — but the v3 grid never reloaded). The Settings **Rescan / Full Rescan** handlers only refreshed the classic (v2) library via `loadLibrary()`; the v3 grid (`static/v3/songs.js`) had no listener for a scan it didn't start itself (only its own upload path self-refreshed via `watchUploadScan`), so its cached, pre-DLC (empty) DOM/snapshot survived a sidebar return until a full reload. The rescan handlers now emit a **`library:changed`** event (`static/app.js`); the v3 grid listens and **reloads if it's the active screen, else marks itself dirty** so the next entry does a full re-fetch instead of restoring the stale snapshot (a `_libraryDirty` short-circuit ahead of every cached-DOM fast-path in `onV3SongsScreenEnter`). Tests: `tests/js/v3_library_refresh.test.js` (the emit + the reload/dirty wiring).
-- **Edit Metadata modal: the Year is now editable.** You could set a year when authoring a pak but the Songs → Edit Metadata modal had no Year field, so it could never be changed afterward. The backend (`POST /api/song/<f>/meta`) already accepted and normalized `year` (writes it into the file via `songmeta`, survives a rescan) — only the UI omitted it. Added a **Year** input to `openEditModal()` (populated from the song's existing year) and included `year` in `saveEditModal()`'s POST body (`static/app.js`). Both the v3 card menu and the legacy edit button already pass the year through, so both surfaces get the field.
-- **Edit Metadata modal no longer closes when a click-drag is released on the backdrop.** Selecting text inside a field and releasing the mouse past the modal's edge dismissed the form without warning (the `click` event's target resolved to the backdrop), discarding the edit. Backdrop dismissal now requires the **mousedown to have started on the backdrop** too — tracked per-modal and decided by a new pure `_editModalShouldClose(clickTarget, modalEl, downOnBackdrop)` helper (`static/app.js`). Cancel / ✕ still close on a normal click. Tests: `tests/js/edit_metadata_modal.test.js` (year in the POST body + the backdrop-close decision table).
-- **Built-in diagnostic sloppak rebranded "Slopsmith" → "FeedBack" in the song name.** PR #586 renamed the file to `feedBack-diagnostic-basic-guitar.sloppak` but never regenerated the archive, so the manifest inside still carried `title: Slopsmith Diagnostic — Basic Guitar` / `artist: Slopsmith` (and the same heading in `DIAGNOSTIC.md`) — the stale name testers saw in the library/player and the onboarding calibration step, even though the build script, server, and docs all already say "FeedBack Diagnostic — Basic Guitar". Regenerated `docs/diagnostics/feedBack-diagnostic-basic-guitar.sloppak` from `docs/diagnostics/build_diagnostic_basic_guitar.py` so the committed artifact matches its source generator (title/artist/heading now "FeedBack"; chart, stem, and `diagnostic:` metadata unchanged). No code change — the rename in #586 just needed the rebuild.
-- **v3 song/lesson accuracy badges now refresh on the first return from a song — no restart needed.** PR #574 added a `stats:recorded` → in-place badge repaint, but the repaint never matched a card. The event (like `song:loading`) carries the filename **`encodeURIComponent`'d** — exactly as `playCard` hands it to `playSong` (the highway WS `decodeURIComponent`s it back) — whereas library cards key on the **decoded** `localFilename` (`data-fn`), and `/api/stats/best` is server-canonicalized to that same decoded key (`server.py` `_canonical_song_filename`). So `repaintAccuracy`'s `data-fn !== key` check rejected every card and `state.accuracy[encoded]` was `undefined`, leaving the just-earned badge stale until a full `render()` (app restart / search / re-enter the screen) — which is why it "came back after a restart." `static/v3/songs.js` now decodes the `stats:recorded` filename back into the card / `state.accuracy` key space via a small `decFn` helper before marking dirty and repainting (idempotent for already-decoded names; falls back to the original on malformed input so a real filename containing a literal `%` is never corrupted), so both the immediate repaint and the `onV3SongsScreenEnter` deferred path land on the right card. Tests: `tests/js/v3_songs_score_badge_refresh.test.js`.
-- **Escape now exits a song (and leaves Settings) even when a transport/rail control button holds keyboard focus.** Clicking a player control (Play / FF / RW / Restart) left that `<button>` focused, and `_shortcutDispatchBlocked()` in `static/app.js` treats any focused `INPUT/SELECT/TEXTAREA/BUTTON` as an "interactive control" and bails before the shortcut registry runs — so the player-scope `Escape → Back` shortcut never fired until the user clicked empty canvas to blur the control ("Escape in song not consistent"). Space already had a player-screen carve-out (#593) that let it fire through a focused control; Escape did not. Generalized that carve-out to Escape, scoped to the player **and** settings screens (both register an `Escape = Back` shortcut, and settings had the identical latent bug). The earlier guards are preserved and still win: text inputs are exempted first (Escape there clears/blurs the field), the Section Practice popover already claims Escape before the carve-out, and a true modal layered over the screen (`[role="dialog"][aria-modal="true"]` / `.feedBack-modal`) still traps Escape so it closes the modal rather than ejecting past it. Escape becomes a reliable, focus-independent "Back" — making it monotonic groundwork for an optional exit-confirm. Plugins that register a player-scope `Escape` shortcut benefit identically (they were broken the same way). Tests: `tests/browser/keyboard-shortcuts.spec.ts` (focused-button repro, text-input no-exit, no-escape-past-modal, Section Practice popover, settings twin-bug).
-- **The v3 "Up Next" pill can now be turned off — new "Show 'Up Next'" gameplay toggle (default ON).** The v0.3.0 player chrome's persistent upcoming-section pill (`#v3-upnext`, drawn by `static/v3/player-chrome.js`'s `updateUpNext()`) shipped with no off switch, so it always showed during playback whenever a section was upcoming — overlapping the top-right FPS HUD and ignoring the 3D-highway "Show 'Up Next' section card" checkbox (a *different*, in-canvas widget that was demoted to default-off precisely because this pill is the canonical readout). Users reading the pill as the same setting saw "disabled in settings but still there." Adds a real core toggle following the `autoplayExit` idiom: a client-only `showUpNext` `localStorage` pref (absence = enabled), a **Show "Up Next"** switch in the Gameplay settings tab (`static/v3/index.html`), reader/writer + `loadSettings()` hydration + a read-only `window.feedBack.showUpNext` getter in `static/app.js`, and a gate at the top of `updateUpNext()` that hides the pill when off. Disabling mid-playback hides it immediately; re-enabling re-shows it on the next chrome tick (~6 Hz). Added to `RESET_MAP.gameplay.local` in `static/v3/settings.js` so the Gameplay "Reset" restores the default-on state. Default ON = zero change for existing users. No Tailwind rebuild (plain markup + existing classes).
-- **v3 list/tree view brought to parity with the grid: select mode, parts chips, and song actions — plus a stale-CSS Docker fix.** Re-lands a previously-reverted change. **Frontend (`static/v3/songs.js`):** entering select mode no longer collapses the tree — `loadTree()` now captures the expanded artist groups (`details[open]` keyed by `data-artist`) before the "Loading…" wipe and restores them on rebuild, so toggling select mode (which re-renders via `reload()`) keeps groups open and selection usable; tree rows gain a display-only checkbox + selection ring, the same fav / save-for-later / overflow-menu cluster as the grid card (always shown, all bound by `wireCards()`), and a capture-phase select guard mirroring the grid so clicking a row or arrangement chip in select mode selects instead of playing (`<summary>` headers sit outside `[data-fn]`, so native expand/collapse is untouched). **Docker fix (`static/tailwind.min.css`):** the committed Tailwind stylesheet was stale — `.sm\:flex` (and the other utilities behind #582's `hidden sm:flex` arrangement chips and the new action cluster) were never compiled in, so they rendered `display:none` on the Docker build (which serves the committed CSS as-is; Desktop rebuilds from source so it looked fine). Regenerated with the pinned `tailwindcss@3.4.19` via `scripts/build-tailwind.sh` so Docker matches Desktop and #582's chips render on every Docker deploy. Regression tests: `tests/browser/v3-tree-select.spec.ts`.
-- **Space bar now plays/pauses on the player screen even when a sidebar nav link or rail button has focus.** When any `<button>` in the player rail (viz, audio, mixer, lyrics, plugins, advanced), a sidebar nav link, or a popover control held keyboard focus, pressing Space was swallowed by `_shortcutDispatchBlocked` → `_isInsideInteractiveControl` (which treats `BUTTON`/`A` as interactive), so the Space shortcut never reached the dispatcher and `togglePlay()` never ran. `_shortcutDispatchBlocked` (`static/app.js`) now extends the same carve-out already used for the Section Practice bar: while the player screen is active, Space is always routed through the shortcut system — the dispatcher calls `e.preventDefault()` before invoking the handler, so the focused element does not also activate. Text inputs (`_isTextInput`) remain exempted first, so typing space in a search/input field still works normally, and focus inside a true modal dialog (`role="dialog" aria-modal="true"` / `.feedBack-modal`) layered over the player is also exempted so Space reaches the modal's focused control (e.g. its Close button) instead of toggling playback behind it — non-modal player popovers/toasts (loop A/B, arrangement pin) stay covered. Regression tests in `tests/browser/keyboard-shortcuts.spec.ts` cover the focused-rail-button play/pause, the text-input exemption, and the modal-dialog exemption.
 - **A song's accuracy badge now updates on its library card right after you play it — no restart needed.** The v3 library (`static/v3/songs.js`) loaded the best-accuracy map (`/api/stats/best`) once into `state.accuracy` at render time and only ever refreshed it on a full re-render; the play→return flow takes the screen-entry fast-path that restores the cached grid DOM without re-fetching, so a just-earned score stayed invisible until the next restart re-ran `render()`. The `stats-recorder` now emits a `stats:recorded` event (carrying `filename`/`arrangement`) once the scored `POST /api/stats` resolves on the server — the correct moment, since `song:stop` fires before the POST completes. `songs.js` listens: if the library is the active screen it re-fetches `/api/stats/best` and patches the affected card/row badge in place; otherwise it marks the filename dirty and `onV3SongsScreenEnter` applies it on return (a failed fetch keeps the entry dirty to retry). Badge markup was factored into a shared `accuracyBadge(filename, variant)` (grid pill + tree-row percentage, both tagged `.fb-acc-badge`) so the in-place `repaintAccuracy` can find and replace them without a full list re-render (scroll/pagination preserved). The old empty `song:stop` "refresh lazily next render" placeholder is replaced.
 - **Changing Settings → 3D Highway → Fret spacing no longer ejects you to the home screen.** The `highway_3d` plugin's `h3dSetFretSpacing` was the lone 3D-highway setting that called `location.reload()` to apply — and since the SPA boots with `#home` as the active screen (`index.html` `.screen.active`), the reload dropped the user out of Settings onto the homescreen. It now applies live like every other 3D-highway setting: it rebinds the module-scope `_h3dFretUniform` flag (so panels mounted later this session pick up the new mode), recomputes the two `fretX`-derived scalars that were baked at init (`_fretLabelScaleRefW` for fret-label sprite scaling, `FRET_WIDTH_MID` for camera hysteresis), and broadcasts a `fretSpacing` change over the existing `_bgEmitChange` pub-sub so every mounted panel rebuilds its board via `buildBoard()`. Per-frame note geometry already reads `fretX` live and needs no rebuild. No page reload, so the Settings screen stays put. Source-level regression tests in `tests/js/highway_3d_fret_spacing.test.js` now pin the no-reload / live-rebuild behavior.
 - **v3 library scroll-restore no longer breaks the classic v2 UI or drops off-screen searches** (feedBack#857). Two regressions in the scroll-restore work above: (1) `playSong` remapped `home`-launched songs to return to the `#v3-songs` screen unconditionally, but `static/app.js` is shared with the v2 UI (served at `/v2` / `FEEDBACK_UI=v2`) where that screen does not exist — Esc-from-player then called `showScreen('v3-songs')`, which threw on the missing element and stranded the user on a blank screen with playback still running; the remap now applies only when `#v3-songs` is present. (2) The Songs screen-entry fast-path skips reloading to preserve scroll, but the global topbar search routed through it, so once Songs had been visited, searching from another screen navigated there without applying the new query; the screen now tracks the state hash each fetch reflects and refetches when it has drifted, keeping the scroll-preserving no-op only when nothing changed.

 - **Screensaver no longer kicks in during windowed-mode playback** (#686). While a song is playing, `static/app.js` now holds a [Screen Wake Lock](https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake_Lock_API) (`navigator.wakeLock.request('screen')`) so the OS display/screensaver stays awake even though only audio + the highway animation are active and the keyboard/mouse are idle. The lock is acquired on `song:play`/`song:resume` and released on `song:pause`/`song:ended`/`song:stop` (kept only while actually playing), and re-acquired on `visibilitychange` when the tab refocuses (the API auto-releases a lock whenever the page is hidden). Both the HTML5 `<audio>` and JUCE desktop playback paths emit the same `song:*` events, so the fix covers both. In feedBack-desktop (Electron), where `navigator.wakeLock` is unreliable, it also drives a native `powerSaveBlocker` bridge via the optional `window.feedBackDesktop.power.setScreenAwake` hook when present; both calls degrade silently where unsupported. Note: the browser Wake Lock API is secure-context only, so in a plain browser this is active on `localhost` / HTTPS only — a session opened over plain HTTP to a LAN IP (e.g. `http://192.168.1.100:8000`) won't keep the screen awake; front it with HTTPS or use the desktop app (see README → reverse-proxy notes).
 
 ### Changed
-- **Practice plugin first-class sidebar slot now points at Virtuoso.** The bundled practice plugin was rebranded/re-homed from the SlopScale fork (`id: slopscale`) to `got-feedback/feedBack-plugin-virtuoso` (`id: virtuoso`); the desktop bundle swap is feedBack-desktop#31. `static/v3/shell.js` still promoted `slopscale`, whose id no longer ships — so `renderPromotedNav()` (gated on the plugin appearing in `/api/plugins`) would have found no match and the dedicated sidebar slot would have gone dark, dropping Virtuoso to the generic Plugins gallery. Update the NAV entry + `PROMOTED_PLUGINS` slot `slopscale` → `virtuoso` (`screen: plugin-virtuoso`, label "Virtuoso - Practice", same FeedBarcade anchor + `target` icon) so the practice plugin keeps its first-class entry. Also clear the now-dead `slopscale` id from the Plugins-gallery curated category map (`static/v3/plugins-page.js`) and add `virtuoso: 'practice'` as a defensive fallback (the manifest's `category: "practice"` is authoritative, so it lands on the practice board regardless), and refresh the stale SlopScale references in `README.md` + `docs/plugin-capability-inventory.md`. Must land with the bundle swap or the practice plugin regresses in the UI.

Must land with the bundle swap or the practice plugin regresses in the UI.
 - **3D highway: realistic curved metal frets.** The fret wires are now bowed `TubeGeometry` (the middle strings push away from the camera so the row of frets reads as wrapping a cylindrical neck — a depth cue) rendered with a lit `MeshStandardMaterial` instead of the old flat, straight `MeshBasicMaterial` boxes, so the scene's ambient + directional light glints across the rounded surface for a polished-steel look. The existing per-frame highlight is preserved unchanged: frets inside the active anchor still turn gold (`0xD8A636`), which under the metallic shading reads as brass. Metalness is kept moderate (0.4, not full-metal) because the scene has no envMap — a PBR full-metal surface would reflect black — with a dim emissive floor so frets stay legible down the fogged neck. Backported from the `highway_babylon` plugin's "hit-zone fret bars". All knobs (`FRET_BOW_DZ`, metalness/roughness/emissive) are tunable constants. `plugins/highway_3d` v3.25.0.
 - **3D highway: section + tone HUD cards now default OFF.** The v0.3.0 player chrome carries a persistent "Up Next" pill, making the in-canvas section card redundant by default (it doubled the readout, feedBack feedback); the tone HUD follows the same less-is-more default. Both remain available in Settings → 3D Highway (visibility/position/size unchanged); users who previously toggled either explicitly keep their stored preference — only the untouched default flips. `plugins/highway_3d` v3.24.1.
 - **Perf**: replace runtime Tailwind Play CDN with a prebuilt static stylesheet (`static/tailwind.min.css`). The Play CDN's runtime JIT scanned the DOM ~1.8x/sec on the main thread (~37 ms blocking spans), dropping ~26% of frames in long playback sessions with the 3D highway as default. Theme extensions (dark/accent/gold colors, Inter font) move to `tailwind.config.js`; regen via `bash scripts/build-tailwind.sh`. No runtime build step — the generated CSS is committed. Fixes feedBack-desktop#110.
 - **Perf**: reduce per-frame allocations in the 2D highway chord + lyric render paths. `_ensureChordRenderCache` now also caches `sortedNotes` / `nonZeroNotes` / `nonZeroFrets` / `allMuted` / `hasMultipleNotes` (computed once per chord, invalidated on `src` / `_inverted` / `chordTemplates` change — the third key catches a stale `isOpen`-derived classification when the WS `chord_templates` message lands after the final `chords` chunk), so `drawChords` no longer re-sorts / re-filters / spreads min-max per visible chord per frame. The in-chord unison bend classification is folded inline (no `chordPositions.filter` × 2 per frame). `drawLyrics` memoizes `ctx.measureText` results in a two-level `Map<fontSize, Map<text, width>>` so cache hits don't allocate a composite string key. Lit-sustain shimmer in `drawSustains` swaps the 4 per-note-per-frame `Math.random()` calls for a 64-entry precomputed jitter LUT (xorshift32-seeded — the LUT contents are reload-stable and test-reproducible; rendered shimmer is deterministic per `createHighway()` instance, since the seed includes that instance's `_frameIdx`) indexed by `(frameIdx + n.s + ⌊n.t·60⌋)`, visually indistinguishable and allocation-free.
-- **Perf**: the load-adaptive render scale (`_adaptRenderScale`, #654) no longer visibly hunts up/down on passages that hover near the frame budget (testers saw "quality going up and down" with the 3D highway). Downscaling stays prompt to protect the frame rate, but **upscaling is now lazy**: a smaller step (×1.06 vs ×1.1) on a longer cooldown (`_AUTO_UPSCALE_COOLDOWN_MS` 2500 ms vs the 600 ms adjust cooldown), reset on any downscale, and gated by a predictive guard — it only upscales when the projected cost *after* the step (≈ cost × step², since draw cost tracks the pixel count) still clears the high budget. The scale therefore settles just inside the 7–12 ms deadband instead of oscillating across it. No new public API; the `_autoScaleMin` "Min res" floor is unchanged.
-
-### Removed
-- **`c` library hotkey ("Convert to .sloppak") removed from core.** Core hardcoded a plugin-specific shortcut: a documentation-only `registerShortcut({ key: 'c', scope: 'library' })` no-op plus a `c → button.sloppak-convert-btn` entry in the library keydown handler that fired the Sloppak Converter plugin's button. Per the plugins-own-their-behavior principle, core no longer ships this hotkey — the convert button still works by click, and the Sloppak Converter plugin can register its own `c` shortcut via `window.registerShortcut()` if keyboard access is wanted. The `f` (favorite) and `e` (edit) library hotkeys, which drive core buttons, are unchanged. Help-modal/registry tests in `tests/browser/keyboard-shortcuts.spec.ts` updated to drop the `c` assertions.
 
 ### Added
 - **Player progression: Mastery Rank, instrument-path challenges, daily/weekly quests, Decibels currency, cosmetics shop (spec 010).** Onboarding gains two steps: pick one or more **instrument paths** (Guitar / Bass / Drums — data-driven, more can ship as content) and a **calibration challenge** offer (play the bundled FeedBack Diagnostic with note detection at 100% accuracy — or skip; either way you reach **Mastery Rank 1**, and a skipped calibration can still be completed later from the Progress screen). Each path levels by completing a content-defined number of **challenges** (any order) from that level's set; Mastery Rank = onboarding rank + the sum of path levels, starting at 0 on a fresh install. The existing unified XP backend is untouched but the frontend renames it to **Decibels (dB)** — a spendable currency earned ONLY by playing (songs, FeedBarcade rounds, quest rewards; no real-money path exists or may be added) — with spend tracked in a separate wallet so lifetime earnings stay monotonic. Rotating **daily/weekly quests** (deterministic per period, lazy instantiation, local-midnight / Monday resets) award dB and feed `quest_completed` challenges. A new **Progress** screen (rank hero, per-path checklists, quest countdowns, add-a-path) and **Shop** screen (themes via CSS-variable swaps under `html[data-fb-theme]`, avatar frames; atomic balance-checked purchases — 402 on insufficient dB, 409 on re-buy) join the v3 nav, and the topbar badge now shows Rank + challenge-set progress + dB balance. All definitions live in `data/progression/` JSON (paths/levels/challenges, quest pools, shop catalog) — adding a rank, challenge, quest, or cosmetic is a content edit + restart, never code; invalid content degrades to logged warnings. New tables (additive + idempotent): `progression_state`, `player_paths`, `challenge_progress`, `quest_state`, `wallet`, `shop_owned`, `shop_equipped`. New endpoints: `GET /api/progression`, `POST /api/progression/paths|onboarding|events` (events whitelists `minigame_run`; `song_completed` stays server-derived inside `POST /api/stats`, which now resolves the instrument server-side and reports an additive `progression` outcome key), `GET /api/shop`, `POST /api/shop/buy|equip`; equipped cosmetics ride along on `GET /api/profile`. A new **`progression` capability domain** (core-owned, kind: command, safety: safe — `inspect`, `record-event`, `list-shop`, `buy-item`/`equip-item` gated on user action) emits `challenge-completed`/`quest-completed`/`path-level-up`/`rank-changed`/`db-changed`/`calibration-completed`/`cosmetic-equipped`, mirrored as `progression:*` window events, with a redaction-safe diagnostics contributor; backend plugins get the symmetric `record_progression_event` context hook (the bundled minigames hub reports runs through it, guarded for standalone). Spec: `specs/010-progression-domain/`. Tests: `tests/test_progression.py`, `tests/test_progression_api.py`. **Migration notes:** existing XP totals carry over as lifetime dB (balance = lifetime − spent); resetting a per-source XP contribution (e.g. a minigames profile reset) after spending can clamp the spendable balance to 0 until new dB is earned; drums-path v1 content uses currently-satisfiable goals (arcade rounds, quests, any-instrument plays) until drums scoring lands.

Tailwind is served as a **prebuilt** stylesheet (`static/tailwind.min.css`, regenerated by `bash scripts/build-tailwind.sh`), **never** the runtime Play CDN — the CDN's on-the-fly JIT rescanned the DOM on the main thread and dropped ~26% of frames with the 3D highway (feedBack-desktop#110). The committed CSS only contains classes the build scanner saw, so CI (`tailwind-fresh`) rebuilds and diffs it; run the build script and commit when you add new classes. A plugin that uses classes not guaranteed in core (notably arbitrary values like `w-[37px]`) MUST ship its own compiled stylesheet via the `styles` manifest key, built with `corePlugins.preflight = false` (utilities only — core ships the one base reset).

-- **Text selection (v3)** — the v3 UI defaults to `user-select: none` on `html` (in `static/v3/v3.css`) so accidental drag/double-click selection of chrome never looks broken. Form fields are always re-enabled, and a **plugin's mounted screen subtree (`.screen[id^="plugin-"]`) stays selectable by default**, so a plugin's copy-worthy text (lyrics, chord names, results, diagnostics) is unaffected — *unless your plugin renders copyable content OUTSIDE its `plugin-<id>` screen* (e.g. injected into the player chrome / a HUD overlay), which inherits the non-select default. Opt such content back in with the core-served **`.fb-selectable`** class (it sets `user-select: text` on the element + descendants; works for runtime-installed plugins since it's hand-authored in core CSS, not a scanned Tailwind utility). Never use a `* { user-select: none }` rule (breaks input carets/IME), and never use `user-select: none` to "lock" text — keep errors, IDs, paths, versions, and metadata selectable. (v2 is unchanged.)
 - **Player layout** — `#player` is `display:flex; flex-direction:column; position:fixed; inset:0`. `#highway` is `flex:1`. `#player-controls` sits at the bottom. Hiding the highway collapses the layout — use `margin-top: auto` on controls if you need to hide it.

-# Host Theme Contract — design proposal
-
-**Status:** proposal (charrette output, 2026-06-29) · **Owner area:** core v3 + plugin UI
-**Trigger:** a plugin UI feature accidentally "carved itself into a single theme."
-
-## 1. Problem
-
-A results-card feature in the `note_detect` plugin (a glow-ring hero button + a
-gradient-filled accuracy number) was built and visually verified against **only the
-default skin** ("neon"). On the other skins it broke: on "esports" — a deliberately
-glow-less, near-monochrome design language — the glow ring and the colour gradient
-simply **vanished**. The colours adapted (everything used CSS custom-property tokens),
-but the **visual devices themselves did not port**, because nothing in the system says
-"this theme does / doesn't do glow rings."
-
-### Root cause (three findings)
-
-1. **Themes are design *languages*, not palettes.** neon = glow + animation + gradients;
-   esports = no-glow, square, near-monochrome amber; metal = brushed steel + hard bevels +
-   drop-shadows. Tokens made *colour* portable; they never made a *device* portable.
-2. **Tokens are named by *device*, not *intent*.** e.g. `--nd-glow-*` holds a glow in neon
-   but a **hard drop-shadow** in metal — the metal skin is already repurposing a
-   device-named slot to express a different language. The cure is to finish that move:
-   name slots by intent, with "off" (`none`) a legal value.
-3. **No "text-legible-on-accent" role.** White-on-accent was hardcoded in several places;
-   on esports' amber accent that's a contrast failure. And `--nd-accent2` was
-   **double-booked** (gradient-end *and* S-grade colour), so the hero gradient resolved
-   amber→near-white and washed out.
-
-A process gap compounds it: **verification covered one skin**, so the regression was
-invisible until a user switched themes. And this recurs ecosystem-wide — other plugins
-ship their own independent skin systems too.
-
-## 2. Current state (two disconnected systems)
-
-| System | What it is | Limits |
-| --- | --- | --- |
-| **Host themes** (`static/v3/theme-core.js`, `html[data-fb-theme]`) | Cosmetic "shop" themes that recolour `fb-*` Tailwind tokens (surfaces/text/borders). | Apply-only & recolour-only. `--fbv-*` vars exist **only while a theme is equipped** (nothing to read in the default state). No read API, no capability signal, no normalized `theme:changed` event. Comment explicitly says it *leaves decorative accents (rings/shadows) at defaults* → **devices are an ownerless gap.** |
-| **Plugin skins** (e.g. `note_detect` `data-nd-skin`) | Full per-plugin design languages (neon/esports/metal) as CSS-var blocks. | Each plugin reinvents the wheel; disconnected from host themes; a feature can't see both. |
-
-## 3. Goals / non-goals
-
-- **Goal:** a feature, authored once, renders correctly in **any** theme — including ones not
-  yet invented — and degrades **intentionally** (neon ring → esports border), never accidentally.
-- **Goal:** the host owns a canonical contract so plugins consume instead of reinventing.
-- **Non-goal:** forcing every plugin skin to become a host theme. Skins stay plugin-local but
-  **implement** the contract.
-- **Non-goal:** backward-compat with pre-v3 hosts. Everything here is additive + feature-detected.
-
-## 4. The contract — three layers
-
-### Layer 1 — Semantic colour **roles** (always present)
-
-The host writes default `--fb-*` role tokens on `:root` **unconditionally** (not only under
-`[data-fb-theme]`), seeded from the canonical `fb` palette, so `var(--fb-accent, …)` always
-resolves — themed or not. Roles:
-
-**Namespace (normative).** The public contract lives under one prefix, **`--fb-*`**, written on
-`:root` by a host-owned *contract stylesheet* (see §6 / §8) so it is present **themed or not**.
-The existing `--fbv-*` vars stay **internal plumbing** — `theme-core.js` uses them only to
-recolour the Tailwind `.bg-fb-*/.text-fb-*/.border-fb-*` utilities under `html[data-fb-theme]`;
-they are **not** part of this contract and plugins must not read them. (Implementation may seed
-`--fb-*` from the same source the `--fbv-*` overrides use, so an equipped theme moves both.)
-
-**Value grammar (normative).** Colour roles are a **space-separated `r g b` triplet** (matching
-today's `--fbv-*` and the Tailwind utilities), consumed as `rgb(var(--fb-accent))` with optional
-alpha `rgb(var(--fb-accent) / .5)`. Recipe slots (Layer 2) hold **full CSS values** for their
-device (a `box-shadow`, a `border` shorthand, a length, a paint), with `none` legal **except**
-where noted.
-
-**Normative role tokens** (all `--fb-*`, all always present):
-
-| Role | Token | Notes |
-| --- | --- | --- |
-| surface / card / border | `--fb-surface` `--fb-card` `--fb-border` | structural |
-| text / dim | `--fb-text` `--fb-text-dim` | |
-| accent / second hue | `--fb-accent` `--fb-accent-2` | `accent-2` is **just a second hue** — never an assumed gradient end |
-| status | `--fb-good` `--fb-warn` `--fb-bad` | maps onto today's palette `good / mid / low` (mid→warn, low→bad) — implementation aliases both |
-| **on-fill (new)** | `--fb-on-accent` `--fb-on-good` `--fb-on-warn` `--fb-on-bad` | **Rule: every role used as a fill behind text gets a paired `--fb-on-*`** (fixes white-on-amber). Required + contrast-linted (§6). |
-| **focus (new)** | `--fb-focus-ring` | focus indicator independent of `accent`, so focus stays visible when `accent ≈ surface` |
-
-### Layer 2 — Capability **recipes** (intent-named slots; "off" is legal)
-
-A theme declares its design *language* by filling intent-named slots (all `--fb-*`-prefixed,
-same namespace as the roles). A feature applies the slot bundle **unconditionally**; it never
-branches on "is this theme glowy?". Atomic slots (renames-by-intent of today's tokens):
-`--fb-corner-radius`, `--fb-corner-clip`, `--fb-panel-shadow`, `--fb-text-emph-shadow`,
-`--fb-panel-texture`, `--fb-motion-decorative` (reduced-motion-gated). For these, `none` is legal.
-
-Two **composite recipes** carry the load:
-
-- **EMPHASIS** — how this theme makes a primary action special:
-  `--fb-emph-fill / --fb-emph-border / --fb-emph-halo / --fb-emph-on`.
-  neon → halo (glow ring); esports → border (solid accent); metal → fill + drop-shadow.
-  Any individual slot may be `none` — but a theme **must** emphasise *somehow* (at least one of
-  fill/border/halo non-`none`), so a primary action is never visually flat.
-- **ACCENT-TEXT** — how this theme fills a big accent number: `--fb-acc-text-fill`
-  (decoupled from `accent-2`). neon/metal → a gradient; esports → a solid accent.
-  **`--fb-acc-text-fill` is the one slot where `none` is illegal** — it is always a valid paint
-  (solid colour or gradient), defaulting to `rgb(var(--fb-accent))`. Reason: the number is
-  rendered with `background-clip: text` + transparent text-fill, so a `none` paint would make
-  the digits **invisible** (transparent fill, nothing to clip) — which would violate the DoD
-  "a device stays legible when its slot resolves to `none`". The feature also feature-detects
-  `background-clip: text` and keeps a solid `color` base (see §5), so the digits are legible
-  even where clip-text is unsupported.
-
-> These generalize the interim per-skin tokens already shipped in `note_detect`
-> (`--nd-hero-ring-idle/on`, `--nd-hero-border`, `--nd-acc-fill`).
-
-### Layer 3 — JS read API + reconciliation
-
-**The JS API is only for renderers that can't use CSS (canvas / WebGL), never for DOM/CSS
-consumers** — those use the tokens and slots directly (§5). Critically, it exposes *resolved
-token values*, **not** theme-style booleans: a `glow:false` flag can't tell a canvas whether to
-draw a border, a bevel, a drop-shadow, or flat text, so there is **no** `capabilities()` of
-booleans. On the existing `window.feedBack` bus:
-
-- `feedBack.theme.get()` → `{ id, isThemed, tokens }` where `tokens` is the **resolved** map of
-  every `--fb-*` role + recipe slot (the computed values, so a canvas reads the actual device,
-  e.g. the gradient stops for `--fb-acc-text-fill`, not a boolean).
-- `feedBack.theme.prefersReducedMotion()` → boolean (host wraps `matchMedia` once). **This is the
-  single approved JS reduced-motion gate going forward** — existing direct `matchMedia` callers
-  (`venue-mood-fx.js`, `pedal-cables.js`) migrate to it; `--fb-motion-decorative` covers the
-  CSS-authored decorative motion.
-- `theme:changed` event → `{ id, tokens }`.
-
-**Lifecycle (normative).** `get()` always returns the **current effective theme synchronously**
-and is valid at any time — before any theme is applied it returns the default/unthemed roles
-(which always exist on `:root`). Theme application is async (it follows a `/api/profile` refresh);
-`theme:changed` fires **only after** the DOM vars/classes are committed, and **once on initial
-hydration** so a late-mounting plugin isn't stuck on stale state. **Plugin rule:** read `get()`
-on mount, then subscribe to `theme:changed` — never assume an order between your mount and the
-first theme apply.
-
-**Reconciliation rule (ends the two-disconnected-systems problem):** a plugin skin
-**derives surface/text/border from host tokens** (`--nd-bg: rgb(var(--fb-card))`, etc.) and
-**owns only its accent + its devices**, selecting the device via the recipe. A host theme then
-pulls plugin chrome along (one truth for surfaces), while the plugin layers identity on top and
-never imposes a device the active theme neutralizes.
-
-**Propagation scope (normative).** The contract is **same-document light-DOM**: `:root` `--fb-*`
-inheritance and the central focus/motion rules (§6) reach any normal plugin screen. A plugin that
-renders into a **shadow root or iframe** is responsible for bridging — copy the resolved
-`get().tokens` into its sub-root and re-subscribe to `theme:changed` (host `:root` vars don't
-cross those boundaries).
-
-## 5. Consumption pattern (the rule for feature authors)
-
-> **A feature may reference a colour *role* or a recipe *slot*. It may never write a raw
-> device — no literal glow `box-shadow`, no literal `linear-gradient`, no hex.** Devices live
-> in slots; the theme owns the slots.
-
-```css
-.hero-cta {
-  background: var(--fb-emph-fill);
-  border:     var(--fb-emph-border);
-  box-shadow: var(--fb-emph-halo);   /* neon→ring · esports→none · metal→drop-shadow */
-  color:      var(--fb-emph-on);     /* never hardcoded #fff again */
-  border-radius: var(--fb-corner-radius);
-}
-.accuracy-number {
-  /* Always-legible solid base; survives no-clip-text support too. */
-  color: rgb(var(--fb-accent));
-}
-/* Apply the clipped paint ONLY where supported — and --fb-acc-text-fill is
-   guaranteed a real paint (never `none`, per Layer 2), so the digits can't go
-   invisible. */
-@supports ((background-clip: text) or (-webkit-background-clip: text)) {
-  .accuracy-number {
-    background: var(--fb-acc-text-fill);
-    -webkit-background-clip: text; background-clip: text;
-    -webkit-text-fill-color: transparent;
-  }
-}
-```
-
-**Where the contract physically lives.** A **host-owned static contract stylesheet** (e.g.
-`static/v3/theme-contract.css`, hand-authored, linked from `static/v3/index.html`) holds the
-always-present `:root --fb-*` defaults **plus** the two central a11y rules below. It is **not** a
-Tailwind file, so it never touches the prebuilt `static/tailwind.min.css` artifact the
-`tailwind-fresh` CI check diffs (and it's independent of `theme-core.js`, which keeps
-runtime-injecting only the `--fbv-*` utility overrides under `[data-fb-theme]`).
-
-- **Reduced motion:** `--fb-motion-decorative` is the *only* place CSS decorative animation is
-  named; one central rule in the contract sheet sets it to `none` under
-  `@media (prefers-reduced-motion: reduce)`, so no theme can forget the gate. (JS-driven motion
-  uses `feedBack.theme.prefersReducedMotion()` — §4.3.)
-- **Focus parity:** one contract-level `:focus-visible { outline: 2px solid rgb(var(--fb-focus-ring)) }`
-  for contract consumers; themes recolour `--fb-focus-ring` but may not author their own focus
-  styling. *Migration:* v3 already ships component-specific focus + reduced-motion rules in
-  `v3.css`; those are reconciled onto the contract token (not magically replaced) as a tracked
-  cleanup — "one rule" describes the end state, not day one.
-- **On-fill contrast:** every `--fb-on-*` is required and **lintable**
-  (`contrast(on-X, X) ≥ 4.5:1`, 3:1 large) for each fill role (`accent / good / warn / bad`).
-  Contrast is the theme's job, computed once — not re-judged per feature.
-
-## 7. Verification gate (prevent recurrence)
-
-- A committed **render-matrix** tool, driven off the runtime skin list, that renders the key
-  surfaces (hero CTA, accent number, **and the canvas share-image card**) across **every skin ×
-  key states** (rest / hover / focus / reduced-motion).
-- The gate is **computed-style invariant assertions** (deterministic, CI-safe) — e.g. "emphasis
-  present and text legible in each theme" — **not** pixel-snapshot diffing (the animated ring +
-  fonts + AA make snapshots flaky); a contact-sheet montage is the human backstop.
-- Triggered on the version bump that CSS changes already require; skins enumerated at runtime +
-  a guard test so the matrix can't silently go stale.
-
-**Definition-of-done for any theme-touching UI change** (the few items that would have caught this):
-expressed via tokens not hardcoded values · rendered across all skins · **a new visual *device*
-stays legible when its slot resolves to `none`** · reduced-motion + focus parity · on-accent contrast.
-
-## 8. Back-compat & rollout
-
-All additive: the new always-present `--fb-*` tokens (in the contract sheet, §6) + a new
-`feedBack.theme` namespace + a new event with no current listeners. Existing plugins (those
-reading `fb-*` Tailwind utility classes, or shipping their own skins) are untouched unless they
-opt in. On a host too old to ship the contract sheet, a consumer still degrades cleanly: the
-two-arg fallback `rgb(var(--fb-accent, 224 128 32))` resolves to the literal, and
-`window.feedBack?.theme?.get?.()` is feature-detected — so older hosts behave exactly as today.
-
-**Workstream (sub-tasks):**
-1. **Host minimal surface** — the contract stylesheet's always-present default `--fb-*` tokens + `feedBack.theme.{get, prefersReducedMotion}` (`get().tokens` = resolved values; no boolean `capabilities()`) + `theme:changed`. *(the smallest thing that would have prevented the incident)*
-2. **note_detect refactor** — rename device tokens by intent (EMPHASIS + ACCENT-TEXT recipes), add `on-accent` + `focus-ring`, derive surfaces from host tokens.
-3. **Verification gate** — commit the render-matrix + DoD checklist; add the canvas share-card surface.
-4. **Ecosystem migration guide** — document the contract + the consumption rule for community plugin authors.
-
-## 9. Cross-apply status (already done)
-
-- `note_detect` results-card hero + accuracy number — fixed via per-skin device tokens
-  (the Layer-2 prototype) and verified across neon/esports/metal.
-- The **canvas share-image card** — re-checked across all three skins: **theme-robust**
-  (reads per-skin colour tokens via computed style, draws skin-neutral solid devices). Minor
-  fidelity gap only: it uses flat `--nd-bg` and skips metal's brushed-steel *texture*.
-
-## 10. Open questions
-
-- Should plugin skins eventually become *selectable host themes* (one picker), or stay
-  plugin-local forever? (This proposal assumes plugin-local + contract-implementing.)
-- Component-recipe **bundles** (per named component) are the richer end-state; intent-named
-  slots are the right seed. When/whether to graduate.
-
-*(Resolved during review and folded into the sections above: the token namespace + value grammar
-and normative role table (§4.1); the `none`-is-illegal carve-out for `--fb-acc-text-fill` (§4.2);
-JS exposes resolved tokens, not booleans (§4.3); `theme:changed` lifecycle + shadow/iframe
-propagation (§4.3); the physical home of the role tokens + central focus/motion rules — a
-host-owned contract stylesheet outside Tailwind (§6).)*

-# Working-tuning — on-device test checklist
-
-The working-tuning series (PRs 1–9) ships with headless unit tests for every state
-machine (`tests/js/working_tuning*.test.js`, `tests/js/tuner_auto_open.test.js`). The
-items below are the parts that **cannot** be covered headlessly — they need a real mic,
-a real instrument, and (for the ASIO item) a specific audio backend. Run these on a
-build before shipping the feature to users.
-
-Prereq: enable the opt-in in **Tuner → settings → "Auto-open on tuning change"** (it's
-off by default). Have a guitar (and a bass, for the per-instrument checks) on hand.
-
-## 1. Auto-open + gate ("tune before you play")
-- [ ] Load a song whose tuning differs from your instrument's current tuning → the tuner
-      **auto-opens** and playback **waits** (does not start underneath it).
-- [ ] Load a song already covered by your tuning → **no** auto-open, playback starts.
-- [ ] **Skip** ("I've tuned") → playback starts, and the tuner badge stops flagging this
-      song's tuning (a working tuning was recorded).
-- [ ] **Back to library** / **Esc** → leaves the song, records **nothing** (re-enter the
-      same song → it still prompts).
-- [ ] Take **longer than 12 s** to tune with the panel open → playback does **not** start
-      underneath you (the fail-open backstop was settled once the panel opened).
-- [ ] Hit **Play** manually while the panel is open → Play wins; no double-start.
-
-## 2. Both-directions retune prompt
-- [ ] From standard, load a Drop-C# song → prompted **down** (E→C#). Tune down, Skip.
-- [ ] Now load a standard song → prompted **back up** (C#→E). (Pre-series, this direction
-      was silent.)
-- [ ] Switch guitar↔bass in the instrument card → each instrument remembers its **own**
-      working tuning; the card label follows the selection (dim = home, amber = retuned).
-
-## 3. Mic-verify (assumed → verified)
-- [ ] With a selected (non-free) tuning, tap **Verify tuning** and play each string in tune.
-      Each string needs ~8 stable in-tune frames (±6 ¢); the per-string progress advances.
-- [ ] Play a string **out of tune** → it never completes; drifting out mid-streak resets it.
-- [ ] Complete all strings → the instrument card's provenance glyph flips to the **filled**
-      (verified) diamond, and the recorded working tuning carries the tuning you verified
-      (not a stale one).
-- [ ] Load the **next** song → the verified state **decays to assumed** (per-session only).
-- [ ] Verify against a **manually-selected** tuning (tuner opened off a song) → the stamped
-      offsets match that tuning, not the last song's.
-
-## 4. Mic contention with note-detection (the ASIO / exclusive-mode risk)
-This is the item flagged in the design charrette: the tuner's mic capture must not starve
-note_detect's scoring input.
-- [ ] Desktop, **ASIO / WASAPI-exclusive** device: auto-open the tuner mid-song, tune, Skip
-      → scoring resumes cleanly; no dropped input, no device-in-use error, no crash.
-- [ ] Shared/`auto` device: same flow → both the tuner and scoring read the mic without a
-      stall.
-- [ ] Leave the tuner's background badge audio running + start a scored song → note_detect
-      still scores (the badge auto-start doesn't hold the device exclusively).
-
-Log the build hash and OS/audio backend with results; file any failure against the

-"""Achievements & Feats of Power — local engine (offline).
-
-State lives under ``<config_dir>/achievements/``:
-  - ``achievements.db``  SQLite — unlocks, activity counters, derived ledger,
-                         and the (PR3) wall sync queue.
-
-Two surfaces, one engine, kept structurally apart (the **integration law**):
-  * **Feats of Power** — activity/volume. The engine OWNS raw activity counters
-    (`counters`), evaluates Feat thresholds, and records Feat unlocks. Feats are
-    the only thing that ever syncs to the public wall.
-  * **Achievements** — demonstrated competency. The engine RECORDS unlocks the
-    source reports (`report-unlock`); it never re-derives them from activity.
-    A baseline catalogue ships here and is driven by the built-in progression
-    system; richer items are contributed by source plugins at runtime.
-
-Endpoints (all under /api/plugins/achievements/):
-  POST /activity        bump activity counters, eval Feats, return newly-unlocked
-  POST /report-unlock   idempotent upsert of a competency/feat unlock
-  POST /report-criterion record a (criterion_id, token) pair → distinct count
-  GET  /catalog         baseline competency defs + earned state
-  GET  /earned          all earned items (id, cls, category, tier, at)
-  GET  /feats           earned Feats (for the profile trophy shelf)
-  POST /remove-me       wipe synced state (full wall-removal lands in PR2/PR3)
-
-Pure threshold/criterion math lives in the sibling ``engine.py`` (P-V testable);
-this module is the SQLite + HTTP shell.

-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see

-# 3D Drum Highway — Mockup
-
-![3D Drum Highway mockup screenshot](screenshots/drum-highway-3d.png)
-
-An exploratory **pure-visual** sibling of `highway_3d`. Renders an 8-lane
-drum highway (7 lanes for hand pieces + a full-width kick bar) populated
-from a hardcoded demo pattern that loops indefinitely. Not yet wired to
-song data, hit detection, audio, or note_detect — this is here to play
-with the look-and-feel.
-
-To see it, load any song in the player, then pick **3D Drum Highway**
-from the viz picker. The mockup animates regardless of what song is
-playing.
-
-## Layout
-
-```
- [HH]  [SNR]  [TM1]  [TM2]  [FT]  [CR]  [RD]    <- 7 lanes, left to right
-   |    |      |      |     |    |     |

- ▓▓▓▓▓▓▓▓▓▓▓▓▓ KICK BAR ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓     <- full-width kick lane
-```
-
-- **Drums** (snare, toms, floor tom): flat disc geometry (`CylinderGeometry`),
-  palette-tinted, with subtle emissive pulse on approach. Snare gets a
-  thin white "wires" stripe.
-- **Cymbals** (hi-hat, crash, ride): faceted gem geometry (truncated
-  `CylinderGeometry`), metallic material, slightly translucent.
-- **Kick**: full-width amber bar across the base, brighter on approach.
-
-## Variants visible in the demo
-
-| Variant | How it reads |
-|---|---|
-| `accent` | Bigger note + white halo ring |
-| `ghost`  | Hollow ring (~65% size) instead of a solid disc |
-| `flam`   | Main note + a small grace disc offset slightly before |
-| `bell`   | Ride only — adds a bright dot in the center of the gem |
-
-The **Fill showcase** demo pattern fires every variant at least once in
-a few bars, plus a tom roll down the kit. Best read of what's possible.

-## Settings (Settings → Plugins → 3D Drum Highway)
-
-- **Palette** — shared 3 palettes with `highway_3d` (default / neon / pastel).
-- **Demo pattern** — rock backbeat / jazz swing / fill showcase.
-- **Camera angle** — 0 (down the lanes) to 1 (top-down). Default 0.35.
-
-All settings persist in `localStorage` under the `drum_h3d_*` prefix.
-
-## What this plugin is *not* doing yet
-
-(Historical note: this started as a pure-visual mockup; it now reads
-`bundle.drumTab` + `bundle.currentTime` and scores MIDI hits against the
-chart, so the old "no song-data wiring" caveats are gone.)
-
-- Sustain trails (drums don't sustain meaningfully)
-- Sticking labels, double kick, rolls — see the TODOs in `screen.js`
-  for the variant backlog
-
-## Ported helpers (keep in sync with highway_3d)
-
-Visual-parity code copied from `plugins/highway_3d/screen.js` — same
-function names, signatures, and constants on purpose, marked with
-`PORTED FROM highway_3d` comments at each site. If the guitar highway
-tunes one of these, mirror the change here (and in `keys_highway_3d`):
-
-- `_bloomEnsure()` / `_bloomDispose()` — EffectComposer + UnrealBloomPass
-  (0.65/0.5/0.82) on a multisampled HalfFloat target, ACES↔None tone-
-  mapping switch in `draw()`; addons dynamic-imported from
-  `/static/vendor/three/addons/` (no CDN fallback — direct render is the
-  graceful degrade)
-
-## Why a separate plugin (vs. drum mode inside highway_3d)?
-
-Cleaner iteration. The drum highway is its own geometry, its own
-gameplay assumptions (lanes ≠ strings, no frets, no chord shapes,
-no sustains), and likely its own chart format. Forking the visuals
-in a sibling plugin lets the mockup move fast without risking
-regressions in the guitar viz that ships today. If the drum highway
-eventually matures, we can decide whether to merge or keep separate.

-A FeedBack (fee[dB]ack) plugin that adds a **Folders** nav screen showing your `.sloppak` / `.feedpak` DLC songs grouped by the folder tree on disk. Create, rename, and delete folders (including **nested subfolders**) directly in the UI, move songs by drag-and-drop, and browse with sort and metadata filters.
-
-> The host app is **FeedBack** (formerly "Slopsmith"). The frontend talks to the host through `window.feedBack`; `window.slopsmith` is a back-compat alias the host still exposes (`window.slopsmith = window.feedBack` in `static/app.js`). New code should prefer `window.feedBack`.
-
-> ⚠️ **Status — bundled core plugin.** This plugin began as a standalone plugin and is now a bundled core plugin. `screen.js` has been unified into a **single surface factory** driving two entry points: the v3 library Folder view (host chrome — host search `#v3-search`/`#lib-filter`, host filter params, renders into `#lib-folder-tree`) and the classic v2 standalone Folders nav-tab (its own `#fb-search` + toolbar, renders into `#fb-tree`). **Folder search works on both surfaces** — typing in the relevant search box re-renders the tree. **Loose-folder songs** (directories with audio + an arrangement XML) are recognised as songs via the host `loosefolder.is_loose_song` predicate, so they appear in the tree alongside `.sloppak`/`.feedpak` bundles. Folder management, nested subfolders, collapsible folders + expand/collapse-all, drag-and-drop, move-song, sort, filters, and the hover metadata badges are wired on both surfaces; verify against a running build before relying on any of it.
-
-## File Structure
-
-```
-plugin.json     Plugin manifest — id, name, nav entry, file declarations ("bundled": true core plugin)
-routes.py       FastAPI backend — recursive DLC scan, folder tree + filters, folder/song mutations, two-level cache
-screen.html     Plugin screen content — injected by the host into the plugin div automatically
-screen.js       Frontend logic — recursive folder tree, search, sort, filters, drag-and-drop, modals
-README.md       User-facing docs
-```
-
-## Architecture
-
-This plugin follows the standard FeedBack plugin pattern (see the repo-root `CLAUDE.md` for the full plugin system reference).
-
-- **Backend** (`routes.py`) — registers routes under `GET/POST /api/plugins/folder_library/`. Uses `context["get_dlc_dir"]()`, `context["extract_meta"]()`, and `context["log"]`. Scans `<dlc>/sloppak/` if it exists, otherwise `<dlc>/`. Recursively walks the tree and handles create/rename/delete folder and move-song operations on slash-separated folder paths.
-- **Frontend** (`screen.js`) — plain vanilla JS in an IIFE. Fetches the tree from the backend on screen load, recursively renders collapsible folder sections (any depth) and song rows or cards (grid view). Uses `window.feedBack.on('screen:changed', ...)` (via the `window.slopsmith` alias) to trigger load when the user navigates here. Calls `window.playSong(filename)` on song click with the full relative path from the DLC root.
-- **No dependencies** — no npm, no build step. Tailwind utility classes available globally from the host; the plugin uses only core-guaranteed utilities and inline styles, so it ships **no** `styles` manifest key.
-
-## Critical Layout Lessons (Hard-Won)
-
-These are non-obvious behaviours of the FeedBack desktop app (Electron) that took significant debugging to discover. They still apply unchanged.
-
-### 1. Do NOT put an outer wrapper div in screen.html
-The host automatically creates `<div id="plugin-folder_library" class="screen">` and injects `screen.html` content inside it. If you add your own outer div with `class="screen"`, you get a nested screen element which gets `display:none` applied, hiding all content.
-
-**Wrong:**
-```html
-<div id="plugin-folder_library" class="screen">
-  <div>toolbar</div>
-  <div>content</div>
-</div>
-```
-
-**Correct:**
-```html
-<!-- no outer wrapper — the host provides it -->
-<div>toolbar</div>
-<div>content</div>
-```
-
-### 2. The .screen CSS class sets display:none by default
-`.screen { display: none }` and `.screen.active { display: block }`. There is no height set. The screen div gets its height purely from its content. Do not try to set height via CSS classes — use inline styles or JS if needed.
-
-### 3. The host navbar is position:fixed with z-index:50
-The navbar sits at `top:0, z-index:50`. Plugin toolbars must use `position:fixed; top:64px; z-index:40` to sit below the navbar. Use a solid `background-color` (not Tailwind bg classes — those may not apply correctly) to prevent content showing through.
-
-### 4. Content must have padding-top to clear the fixed toolbar
-Since the toolbar is `position:fixed`, it floats above the content. The content container needs enough `padding-top` (~120px) to ensure the first item isn't hidden behind the toolbar — the host navbar (64px) plus the plugin toolbar height (~56px). Adding more toolbar buttons increases this height, so if content is clipped, increase the padding further.
-
-### 5. Electron blocks window.prompt() and window.confirm()
-The desktop app is built on Electron, which throws `Error: prompt() is not supported`. Use a custom inline modal instead. See `_showModal()` in `screen.js` — it returns a Promise and supports both text input and confirm modes.
-
-### 6. The nav plugin dropdown has z-index:50 and blocks clicks
-When navigating to a plugin screen via the Plugins dropdown, the dropdown stays open and sits on top of the screen. Call `_closeDropdown()` on screen load to dismiss it. The dropdown element id is `plugin-dropdown`.
-
-### 7. playSong() expects a relative path from the DLC root
-`window.playSong()` expects the path relative to the DLC root with forward slashes, e.g. `sloppak/CH/Artist - Title.sloppak`. Not just the filename. The backend builds this in `_meta()` via `"/".join(p.relative_to(dlc).parts)` and returns it as each song's `filename`.
-
-### 8. FastAPI POST routes need `from fastapi import Request`
-Routes that receive a JSON body must import `Request` from fastapi explicitly and use `async def route(request: Request)` with `body = await request.json()`. Missing this import crashes the server on plugin load.
-
-### 9. Plugin id must be consistent everywhere
-The plugin id (`folder_library`) must match in:
-- `plugin.json` → `"id"` and `"nav.screen"`
-- `screen.js` → `PLUGIN_ID` constant and `API` constant (`/api/plugins/folder_library`)
-- `routes.py` → `APIRouter(prefix="/api/plugins/folder_library")`
-
-A mismatch in any of these causes silent failures (blank screen, 404 API calls).
-
-### 10. Use inline styles for grid layout, not Tailwind
-Tailwind's `grid` and `grid-cols-*` classes may not apply reliably inside the plugin div. Use `element.style.cssText` with explicit `display:grid; grid-template-columns:...` for the grid container.
-
-## Key Conventions
-
-- **IIFE + `'use strict'`** — all frontend code wrapped in `(function(){ 'use strict'; ... })();`
-- **localStorage prefixes** — plugin keys are prefixed `fo:` (e.g. `fo:view`, `fo:sort`, `fo:filters`); host-library-synced filter state uses `fo:lib:`. Open-folder state is tracked by **folder path** (so nested folders each remember their own state).
-- **Safe storage access** — all `localStorage` reads/writes wrapped in try/catch
-- **Logging** — backend uses `context["log"]`, never `print()`
-- **Sibling imports** — use `context["load_sibling"]("name")` not bare `import name` (none needed today; keep this in mind if you add helper modules)
-
-## Song Formats
-
-The plugin treats both `.sloppak` and `.feedpak` as songs (`_is_song()` in `routes.py`). `feedpak` is the published name for the same on-disk format the codebase still calls `sloppak` internally — see the repo-root `CLAUDE.md`. Both file form (`.sloppak`/`.feedpak` zip) and directory form (`*.sloppak/` folder) are recognized.
-
-## Backend Routes
-
-| Method | Path | Description |
-|--------|------|-------------|
-| GET | `/api/plugins/folder_library/tree` | Returns the folder tree. Accepts optional filter query params (below) applied server-side. |
-| POST | `/api/plugins/folder_library/folder/create` | Body: `{name, parent?}` — creates a subfolder; `parent` (slash path) nests it inside an existing folder, omit/empty for top level |
-| POST | `/api/plugins/folder_library/folder/rename` | Body: `{old, new}` — `old` is a slash path, `new` is a bare name; renames within the same parent |
-| POST | `/api/plugins/folder_library/folder/delete` | Body: `{name}` (slash path) — moves all songs at any depth to the scan root, then removes the folder |
-| POST | `/api/plugins/folder_library/song/move` | Body: `{filename, folder}` — moves a song to `folder` (slash path; empty = scan root / "Unsorted") |
-
-### `/tree` filter query params
-
-All optional, applied server-side over the cached full tree by `_apply_tree_filters()`. Comma-separated, case-insensitive:
-
-- `arrangements_has`, `arrangements_lacks` — include/exclude by arrangement name
-- `stems_has`, `stems_lacks` — include/exclude by stem name
-- `has_lyrics` — `""` (any), `"1"`, or `"0"`
-- `tunings` — comma-separated tuning names to include
-
-The frontend forwards the host library's active filter params here (via `window.feedBackLibFilterParams()` when present, with `window.slopsmithLibFilterParams()` as a legacy fallback) so the Folders view can stay in sync with the main library filters, falling back to its own filter panel state otherwise.
-
-### Path safety
-
-`_safe_name()` rejects empty names, leading/trailing whitespace, the characters `\ / : * ? " < > |`, and `.`/`..`. `_safe_path()` applies `_safe_name()` to every slash-separated segment, so traversal (`..`) and absolute paths are rejected before any filesystem op. Always validate user-supplied folder paths through these before touching disk.
-
-## Tree Shape
-
-`/tree` returns:
-
-```json
-{
-  "folders": [
-    {
-      "name": "CH",
-      "path": "CH",
-      "songs": [ /* song objects */ ],
-      "children": [
-        { "name": "Live", "path": "CH/Live", "songs": [], "children": [] }
-      ]
-    }
-  ],
-  "root_songs": [ /* songs sitting directly in the scan root — shown as "Unsorted" */ ]
-}
-```
-
-Folder nodes are **recursive**: each has `name`, `path` (slash-separated, relative to the scan root), `songs`, and `children`. The frontend renders any depth — `_findFolderByPath()`, `_countDeep()`, and `_countFoldersDeep()` walk the `children` arrays.
-
-## Song Metadata Format
-
-Each song object (built by `_meta()`):
-
-```json
-{
-  "filename": "sloppak/CH/Artist - Title.sloppak",
-  "title": "Title",
-  "artist": "Artist",
-  "album": "Album Name",
-  "duration": 213.5,
-  "year": 1993,
-  "tuning": "E Standard",
-  "added": 1748132400.0,
-  "arrangements": ["Lead", "Rhythm", "Bass"],
-  "stems": ["Drums", "Bass", "Vocals"],
-  "lyrics": true
-}
-```
-
-- `filename` is the full relative path from the DLC root — pass it directly to `window.playSong()`.
-- `added` is a Unix timestamp (float, seconds) from `stat().st_mtime` — convert with `new Date(added * 1000)`. Always recomputed fresh (it changes when a file moves), even on a metadata-cache hit.
-- `arrangements` / `stems` are flat lists of **strings**, even though `extract_meta()` returns them as objects.
-
-### extract_meta returns arrangements/stems as objects, not strings
-
-`context["extract_meta"]()` returns arrangements as a list of objects `{index, name, notes}`, not plain strings; stems similarly. `_meta()` normalizes to `.name`:
-
-```python
-raw_arr = raw.get("arrangements") or []
-m["arrangements"] = [
-    a["name"] if isinstance(a, dict) else str(a)
-    for a in raw_arr
-    if (isinstance(a, dict) and "name" in a) or isinstance(a, str)
-]
-```
-
-`lyrics` is coerced to a bool from several possible keys (`lyrics`, `hasLyrics`, `has_lyrics`, …). If you add new metadata fields from `extract_meta`, check the raw shape before assuming it's a plain value.
-
-## Two-Level Cache
-
-`routes.py` keeps two caches inside `setup()`:
-
-- **`_meta_cache`** — expensive `extract_meta()` results keyed by absolute POSIX path. **Never cleared.** When files move (rename/delete/move), the keys are rewritten in-place so the warm data survives the operation.
-- **`_cache`** — the assembled tree structure (`folders` / `root_songs`). Cleared by `_invalidate()` on **every** mutation so the next `/tree` rebuilds it — but the rebuild is fast because `_meta_cache` is still warm.
-
-`filename` and `added` are deliberately **not** stored in `_meta_cache` (they depend on the file's current location) — they're recomputed on every `_meta()` call and merged onto the cached copy. When you add a mutation route, mirror the existing key-rewrite logic (see `rename_folder`, `delete_folder`, `move_song`) so the metadata cache stays valid.
-
-## Folder Scan Logic
-
-`routes.py` scans recursively starting at `<dlc>/sloppak/` (or `<dlc>/` if no `sloppak` subdir exists):
-- Files/dirs matching `.sloppak` or `.feedpak` → song entries (root-level ones go to `root_songs`, shown as "Unsorted")
-- Subdirectories → recursive folder nodes with their own `songs` + `children`
-- Dot-prefixed entries are skipped; empty folders are still included (shown with a 0 count)
-
-To add more grouping options (by artist, album, etc.), build an alternative projection over the scanned songs rather than the on-disk tree.
-
-## Library provider (future, not implemented)
-
-This plugin surfaces folders as a dedicated **view** over the existing library;
-it does not (yet) register itself as a selectable library **source/provider**.
-If you want a "Folders" entry to appear in the host's main library-source
-picker (mapping top-level folder → "artist", subfolder → "album"), implement a
-provider exposing the source-aware contract (`query_page`, `query_artists`,
-`query_stats`, `tuning_names`) and register it in `setup()` via
-`context["register_library_provider"](...)`, unregistering on teardown. (An
-earlier inert `FolderLibraryProvider` scaffold was removed — it was never wired
-and only duplicated the scan logic; re-add it only alongside real registration
-and tests.)
-
-## View Modes (List / Grid)
-
-The toolbar has a list/grid toggle. Current view is stored in `localStorage` under `fo:view` (`'list'` or `'grid'`).
-
-- **List view** — `_songRow()`, rendered inside a `ml-5 space-y-0` div
-- **Grid view** — `_songCard()`, rendered inside a CSS grid div (`auto-fill, minmax(150px,1fr)`)
-- Both the folder and unsorted section renderers branch on `_view` to pick the right renderer and container
-- Album art is fetched via `/api/song/<encoded-path>/art` where each path segment is individually `encodeURIComponent`-encoded. On error the `<img>` is hidden and a placeholder SVG is shown
-- The collapse/expand toggle restores `display:grid` (not just `display:''`) when reopening a folder in grid mode — always check this when changing toggle logic
-
-### Lazy folder rendering
-
-Folders do **not** render their song list on initial load. The folder renderer sets a `_listPopulated` flag and only populates the list the first time a folder is opened, keeping the initial render fast with large libraries. When search is active all folders are forced open and populated immediately (search overrides lazy loading).
-
-## Sort System
-
-The toolbar has a sort select (`#fb-sort`) and a direction toggle (`#fb-sort-dir`). State is stored under `fo:sort` and `fo:sortDir`.
-
-- `_sort` — `'default' | 'title' | 'artist' | 'duration' | 'year' | 'tuning' | 'added'`
-- `_sortDir` — `'asc' | 'desc'`
-- `_sortSongs(songs)` returns a sorted copy; direction is applied by reversing after sort. Returns the array unchanged when `_sort === 'default'`.
-- The sort direction button is dimmed (`opacity: 0.35`) and non-interactive when sort is `'default'`.
-
-## Filter System
-
-Client-side filters are stored under `fo:filters` as a JSON object. (The server `/tree` endpoint can also filter — see Backend Routes — used to sync with the host library.)
-
-### Filter state shape
-
-```js
-_filters = {
-    arrangements: { Lead: 'on', Bass: 'exclude', Rhythm: 'off' },
-    stems:        { Drums: 'off' },
-    lyrics:       'off',   // 'off' | 'on' | 'exclude'
-    tunings:      ['E Standard', 'Eb Standard'],
-}
-```
-
-Each arrangement/stem value is `'off' | 'on' | 'exclude'`.
-
-### Include vs exclude logic
-
-`_matchFilters(song)` uses **OR logic for includes, AND logic for excludes**:
-
-- **Include (`'on'`)** — song passes if it has *at least one* selected arrangement/stem. More includes widens the result set.
-- **Exclude (`'exclude'`)** — each excluded tag independently removes songs that have it. More excludes narrows the result set.
-
-This matches standard multi-select filter UX (Spotify/library style).
-
-### Data-driven filter panel
-
-All filter sections are built from the actual library data — nothing is hardcoded:
-
-- `_getArrangements()` — unique arrangement names sorted by frequency (most common first), then alphabetically
-- `_getStems()` — same pattern for stem names
-- `_getAvailableFilters()` — returns `{ arrangements, stems, lyrics, tuning }` booleans gating the lyrics/tuning sections
-
-Non-standard arrangement names (e.g. `"Bonus"`) appear as pills automatically — no constants to update. The stems section only appears if at least one song has stems data.
-
-### Split pill UI
-
-`_makeSplitPill(label, state, onChange)` renders a two-zone pill:
-- Left zone (label) — toggles `'off' ↔ 'on'` (include, blue)
-- Right zone (`✕`) — toggles `'off' ↔ 'exclude'` (exclude, red)
-
-The filter badge (`#fb-filter-badge`) shows the active filter count via `_activeFilterCount()`.
-
-## Hover Badges
-
-Each song row/card has two hidden hover-reveal layers, built once and toggled via CSS `max-height` + `opacity` transitions.
-
-### `_badge(text, active, type)`
-
-Renders a single metadata badge. Type controls the inactive colour:
-
-| type | inactive border | inactive text |
-|---|---|---|
-| `'arrangement'` | amber `#92400e` | amber `#fcd34d` |
-| `'stem'` | violet `#5b21b6` | violet `#c4b5fd` |
-| `'lyrics'` | rose `#9f1239` | rose `#fda4af` |
-| `'tuning'` | teal `#0f766e` | teal `#5eead4` |
-
-Active state is always blue (`#1d4ed8` fill, `#3b82f6` border, white text) regardless of type.
-
-### `_buildSongBadges(song)`
-
-Builds the badge row (arrangements, stems, lyrics, tuning), deduplicating within each category. Clicking a badge toggles that filter on/off and re-renders. Returns `null` if the song has no filterable metadata.
-
-### `_buildSongDateInfo(song)`
-
-Builds a separate plain-text hover line showing `year · date added` (e.g. `1993  ·  24 May 2026`), `#cbd5e1` text. Always shown on hover regardless of filter state.
-
-### Reveal / hide
-
-```js
-_revealBadges(el)  // max-height:120px, opacity:1, margin-top:4px
-_hideBadges(el)    // max-height:0, opacity:0, margin-top:0
-```
-
-Both badge layers (badges + date-info) are wired to the same `mouseenter`/`mouseleave` events on the row or card element.
-
-## Drag-and-Drop
-
-Drag-and-drop uses **pointer events** (mousedown/mousemove/mouseup), not the HTML5 DnD API. HTML5 DnD blocks wheel events and gives unreliable edge positions inside Electron — pointer events give full control.
-
-- `_makeDraggable(el, song, folderName)` — attaches a `mousedown` listener. A drag goes "live" only after the pointer moves more than `_DRAG_THRESH` (5 px), preventing accidental drags on clicks.
-- Once live, a ghost `div` follows the cursor. Auto-scroll activates when the pointer is within `_DRAG_ZONE` (150 px) of the viewport top/bottom.
-- `_makeDropTarget(el, targetFolder)` — sets `data-dropFolder` so an element can receive drops. Both folder headers and song-list containers are drop targets — including **nested** folders (drop onto a subfolder header moves the song there).
-- `_dragFindTarget(x, y)` — uses `document.elementsFromPoint` to find the topmost element with `data-dropFolder` under the cursor.
-- **Esc to cancel** — `_onDragKeyDown` calls `_endPointerDrag()` on `Escape`, removing the ghost and clearing state without dropping.
-- On a successful drop, `_executeDrop()` does an **optimistic UI update** (moves the song in the in-memory tree and re-renders) then calls `/song/move`. On API failure it reloads the full tree.
-- A one-time `click` capture listener after mouseup suppresses the post-drag click so it doesn't trigger playback.
-
-## Modal Behaviour
-
-`_showModal(msg, withInput, defaultVal)` is the custom modal used for all prompts and confirms (Electron blocks `window.prompt()` / `window.confirm()`). It returns a Promise.
-
-- `_confirm(msg)` — resolves `true` on OK, `null` on cancel
-- `_prompt(msg, default)` — resolves the trimmed input string on OK, `null` on cancel
-- **Esc cancels** — resolves with `null`, same as Cancel (applies to rename, delete, create folder/subfolder, move song)
-- **Enter confirms** — submits, equivalent to OK
-
-## Roadmap
-
-Implemented since the original release: **nested subfolders** (recursive tree + create-inside-folder), drag-and-drop, sort, advanced filtering, server-side tree filtering synced to the host library, and the warm metadata cache.
-
-Not yet implemented, in rough priority order:
-
-- **Auto-play on hover** — with an on/off toggle saved to localStorage.
-- **Bulk move** — multi-select songs and move them all at once.
-- **Thumbnail performance** — faster loading and smoother scrolling with large libraries.
-- **Adjustable thumbnail/row sizes** — user-resizable song cards and list rows.
-- **Custom themes** — switchable colour schemes.
-- **Favoriting songs** — likely a new backend route plus a `fo:favorites` localStorage key.
-- **Editing song metadata** — edit title, artist, album etc. in-plugin; needs new backend write routes.
-- **Folders as a library source** — register a library provider so a "Folders" entry appears in the host's main library-source picker (see "Library provider (future)" above).

-![Platform](https://img.shields.io/badge/platform-fee%5BdB%5Dack-darkblue)
-
-A FeedBack (fee[dB]ack) plugin that organizes your `.sloppak` / `.feedpak` DLC songs into a folder tree, grouped by the folders on disk. Browse your whole library visually with album art, nest folders as deep as you like, switch between list and grid layouts, and manage folders without ever leaving the app.
-

-
-> **Status — migrating to core.** Folder Library is being reworked from a standalone plugin into a bundled core plugin, and several previously-shipped features are not currently wired up in core (see the Roadmap). The list below reflects what works today; if something here is wrong, it's because this rework is still in progress.
-
-## Features
-
-- **List & Grid views** — toggle between a compact list with thumbnails or a full album art card grid
-- **Album art** — pulls art automatically for every song in both views
-- **One-click playback** — click any song to start playing immediately
-- **Sort options** — sort songs by title, artist, duration, year, tuning, or recently added with an asc/desc toggle
-- **Advanced filters** — filter by arrangements, stems, lyrics, and tuning with include and exclude support
-- **Folder management** — create, rename, and delete folders without leaving the plugin
-- **Nested subfolders** — organize as deep as you want; create a subfolder inside any folder, expand/collapse a whole branch in one click
-- **Collapsible folders** — expand/collapse individual folders, plus Expand All / Collapse All
-- **Move songs** — reassign any song to a different folder on the fly; press `Esc` to cancel
-- **Drag-and-drop** — drag songs between folders (including into nested folders) with smooth auto-scroll; press `Esc` to cancel
-- **Fast with big libraries** — folder song lists render lazily and metadata is cached so reopening folders is instant
-

-
-## Installation
-
-Folder Library ships bundled with FeedBack as a core plugin (`"bundled": true`), so there's nothing to install — the **Folders** screen appears in the navbar under **Plugins** automatically.

-## Changelog
-
-Folder Library started life as a standalone plugin with its own version line, but it's now a **bundled core plugin** that ships with FeedBack. Its changes are tracked alongside the app in the repo-root [CHANGELOG.md](../../CHANGELOG.md), and it versions with the app rather than on its own. The **Features** section above reflects what's in the current build.

 - **Section labels** → `update()`, `// ── Section labels ──` block. Cyan (`#00cccc`) sprite at fret 12, above the highest string.
 
-### Scene colors (two independent axes: Background + Highway)
-- **Scene-color themes** → `BG_THEMES` table near the top of `createFactory()`. One combined table is the single source of truth, but it drives **two independent axes that share the same id-set**:
-  - **Background axis** — setting key `bgTheme`, setter `window.h3dBgSetBgTheme`, state `bgThemeId`. Owns `clear` (WebGL clear color) + `fog`.
-  - **Highway axis** — setting key `hwTheme`, setter `window.h3dBgSetHwTheme`, state `hwThemeId`. Owns `board` (fretboard/highway-surface plane) + optional `lane`/`laneDim` (the lit lane strip).
-  Any background id can mix with any highway id; picking the same id in both gives the original "matched" look. Per-axis accessors are `_bgBackgroundColors(id)` / `_bgHighwayColors(id)` (both alias `_bgThemeColors`). Both axes default to `'default'` (byte-identical to the original look).
-- **Applying a theme** → `_applyBgTheme()`. Background half sets clear+fog from `bgThemeId` (skipped under the venue scene); highway half sets the board plane + lane materials (`mLaneOdd`/`mLaneEven`) from `hwThemeId`. Re-run on init, `buildBoard()`, and the settings listener (which fires for **both** `bgTheme` and `hwTheme`), so changing either dropdown retints only its half live.
-- **Backward-compat migration** → `_bgLoadSettings()`: the first time it loads with no stored `hwTheme` (`_bgHasStored` false), it seeds `hwThemeId` from `bgThemeId` **and persists `hwTheme` once** (a one-time backfill, written without `_bgEmitChange`). So a pre-split single-`bgTheme` pick is byte-identical right after the upgrade, and from then on the two axes are fully independent — changing the Background dropdown never drags the Highway surface, and the settings UI's Highway value can't disagree with what's rendered. settings.html shows the same first-load value via `storedHwTheme == null ? bgTheme : coerceHwTheme(...)`.
-- **Adding/removing a theme** → edit `BG_THEMES` (the colors) AND `settings.html`'s `SCENE_THEMES` array (the `{id,label}` list — the single source the two dropdowns' `<option>`s and the `VALID_BG_THEMES` validator are both generated from). Keep the two id-sets aligned.
-
 ### Highway lane (the highlighted strip under active frets)
 - **Lane drawing** → `update()`, `// ── Dynamic highway lane ──` block. `pLane` is a single quad on the fretboard plane; `pLaneDivider` is thin vertical lines at each fret inside the lane. Width keys off the active-fret range; min width ≈ 4 frets.
-- **Lane intensity** → `highwayIntensity` accumulated from upcoming notes (further notes dim it, near notes light it).
-- **Lane color** → the lit quad color is `mLaneOdd.color` (stock `HWY_LANE_STRIPE_ODD_HEX = 0x103B5C`), the dimmer alternating row `mLaneEven.color` (`HWY_LANE_STRIPE_EVEN_HEX = 0x08283C`). These are now **theme-aware**: `_applyBgTheme()` recolors them from the active HIGHWAY theme's optional `lane`/`laneDim` fields, falling back to the stock hexes when a highway theme omits them. (`_laneTargetColor`, set in `initScene()`, is kept in sync with the lit color but has no live consumer today.)
+- **Lane intensity** → `highwayIntensity` accumulated from upcoming notes (further notes dim it, near notes light it). `_laneTargetColor = 0x4488ff` (set in `initScene()`) is the "lit" color, blended toward from `0x112233`.

 If a planned color-palette feature lands (issue #10), expect it to swap the palette source array but keep this single-array indirection. Anything that hardcodes color today will break that swap; flag it during review.

-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD

-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of

-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.

-# Keys Highway 3D
-
-RS+-style falling-note 3D piano highway for [Slopsmith](https://github.com/got-feedback/feedback), fed by the **Sloppak Notation Format** (sloppak-spec §5.3) — part of the piano/keys first-class epic (slopsmith#828, plugin workstream slopsmith#824).
-
-- Consumes the `notation_info` / `notation_measures` highway-WS stream over a private per-instance socket and flattens measure → staff → voice → beat → note into `{midi, t, durSec, hand}` (durations derived from written `dur`/`dot`/`tu` at the running tempo; ties extend; overlap-clamped).
-- 3D perspective highway to a vanishing point with a real white/black-key keyboard; per-key **pitch-class colours** (Synthesia convention — C red, D yellow, E blue, …) with hand (rh/lh) as a secondary brightness cue.
-- Full RS+ visual treatment: key **letter glyphs** printed on the active-range key tops (cached CanvasTextures), **bevelled gem-style note blocks** (ExtrudeGeometry, geometry/material caches keyed by size and pitch-class×hand), **floating bar numbers** scrolling with the notes, **active-range lane dimming** so the playable span pops, and a **glowing pulsing hit-line** (layered additive gradient planes — no postprocessing).
-- Performance discipline: no per-frame allocations or DOM queries in `draw()`. Chart-scoped resources — note geometries/materials, bar-number and glow textures — are cached and disposed on chart teardown; the key-letter glyph `CanvasTexture`s live in a shared module-level cache that survives teardown and is reused across instances.
-- Auto-selected for arrangements with notation via `matchesArrangement(songInfo.has_notation)`; capability-native `visualization` provider declaration.
-- **Web MIDI input scoring**: module-level MIDI singleton (one access per tab, focused-instance routing) with device auto-connect by saved id+name, loopback blocklist, channel filter, transpose and CC64 sustain (`keys3d_` localStorage prefix; `window.keysH3d*` settings API). Hit detection matches played MIDI against the flattened chart notes within ±0.10 s with per-note dedupe and a missed-note sweep (only while a device is connected — never retroactive across a mid-song connect).
-- **Live hit feedback on the MIDI path** (not the chart): key depress (~4° back-edge pivot, ~120 ms spring; the key letter rides along), wrong-note red key flash, and a vertical flame flare on hits (pooled additive sprites, white-hot base fading into the pitch-class colour, ~400 ms).
-- **End-of-run stats**: POSTs `/api/stats` `{filename, arrangement, score, accuracy}` exactly once per run with the same formula as the guitar notedetect path (`accuracy = hits / max(1, hits+misses)`, `score = round(hits·100·accuracy)`), then notifies the progression core when present.
-- **Capability wiring** (all guarded for servers without the hosts): registers as a note-detection `midi` provider (`keys-midi`, `verify.target`), opens a per-song binding scoped to the chart's keys range, reports hit/miss observability events, and exposes Web MIDI inputs to the audio-input domain with pseudonymized labels (`midi-input-1`, …) via `source.enumerate/describe/open/close`.
-- Headless test hook: `window.__keysHwTest = { injectNoteOn(midi, when), getScore() }`.

-## Tests

-node --test tests/*.test.js
-```
-
-## Ported helpers (keep in sync with highway_3d)
-
-Visual-parity code copied from `plugins/highway_3d/screen.js` — same
-function names, signatures, and constants on purpose, marked with
-`PORTED FROM highway_3d` comments at each site. If the guitar highway
-tunes one of these, mirror the change here (and in `drum_highway_3d`):
-
-- `_bloomEnsure()` / `_bloomDispose()` — EffectComposer + UnrealBloomPass
-  (0.65/0.5/0.82) on a multisampled HalfFloat target, ACES↔None tone-
-  mapping switch in `draw()`; addons dynamic-imported from
-  `/static/vendor/three/addons/` (no CDN fallback — direct render is the
-  graceful degrade)

-// Core "working tuning" capability domain — the live, host-authoritative CURRENT
-// instrument tuning (session state), distinct from the soft opt-in default and from
-// any one song's tuning. This is the single source of truth the whole app reads:
-// the highway, the library/song-picker, Virtuoso, and the minigames all consult it,
-// and the tuner is the sole WRITER (it updates this when the player retunes, clears
-// the gate, or switches instruments).
-//
-// PER-INSTRUMENT: a player has separate physical instruments, each in its OWN tuning
-// ("I'm not tuning two instruments when I pick a song"). So state is a MAP keyed by
-// instrument — `${instrument}-${stringCount}` (e.g. "guitar-6", "bass-4"), the same key
-// the v3 instrument selector uses. `get()` returns the CURRENTLY-SELECTED instrument's
-// tuning; switching the selector surfaces that instrument's own remembered tuning. You
-// only ever deal with the one you've picked.
-//
-// Design: WORKING-TUNING-STATE-DESIGN.md (host-first PR series, PR 1 = this file).
-// Pattern mirrors `capabilities/tuning.js` (capability registration) + the host theme
-// read-API (`window.feedBack.theme`): a synchronous `get()` plus a `working-tuning-
-// changed` event that also fires once on hydration.
-//
-// State is IN-MEMORY and NOT persisted — reset-to-home on restart is deliberate (a
-// stale "you're in drop-A" assumption is worse than re-asking). The opt-in "default
-// tuning on app open" lands later; for now we seed the selected instrument from
-// /api/settings.
-//
-// PR 1 is PURE PLUMBING: it introduces the state + read/write surface + event, but
-// nothing writes to it yet and no behavior changes. The tuner becomes the writer (and

-     composition on WebKit (bug 82692); we scope to `html` and re-enable below.
-   - This is cosmetic only; it protects nothing (DevTools defeats it) and must
