feat(keys_highway_3d): audio-reactive ambience + score FX overlay (K4) (#709)
- BG_STYLES port (off/particles/lights/geometric; lights use the pitch-class palette) mounted behind the scene; _bgGetAnalyser/ _bgReadBands (stems-first, one-shot #audio fallback, permanent-failure latch); Ambience intensity + Audio-reactive settings; remounts on style/intensity change - Score-FX overlay canvas (drum_highway_3d pattern): +1 pops at the scored key, ring pulse every 10-combo, milestone bursts at 25/50/100, red wash on 3+ streak break (wrong notes AND swept misses); cleared when idle, removed in teardown - Tests: style id validation + FX defaults (30 total) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

- **Player frame-time hotspots removed (trace-backed) + weak-hardware hardening.** A Chrome performance trace of a 3D-highway session surfaced two core per-frame layout-thrash sources, now fixed: the highway's visibility check read `canvas.offsetParent` every rAF frame (forces style/layout recalc — now sampled every 10th frame with a cached value, force-refreshed on init/canvas-replace/resize/override-clear), and the v3 player chrome loop called `matches(':hover')` per frame and unconditionally rewrote the Up-Next pill's `textContent`/bar width at 6 Hz (now hover-tracked via mouseenter/mouseleave, DOM writes only on value change, progress bar moved from `width` to compositor-only `scaleX`). The 3D highway pre-warms shader programs (`ren.compile`) and deterministic label textures at init — and chart-dependent chord/section label textures on first draw — so first-appearance shader-compile/texture-upload frame spikes move into the load spinner. For weaker hardware: the per-frame renderer bundle is now a single reused object instead of a fresh ~35-field allocation per frame (object identity is stable and meaningless; array fields still swap reference on chart changes), custom viz get `bundle.lowerBoundT`/`bundle.lowerBoundTime` binary-search helpers for visible-window culling, the default 2D highway's beat lines no longer scan every beat in the song per frame, and the 3D highway stops reading `localStorage` per frame (1 Hz poll) and caches its lyrics text-measurement layout per displayed line instead of re-measuring every syllable every frame. A second, throttled-CPU trace pass additionally removed: shader-program re-resolution churn from label texture swaps (`material.needsUpdate` is now only set on a null↔texture transition — swapping between two cached label textures never changes the compiled program), the 3D highway's per-frame `getBoundingClientRect` layout read in its canvas-size self-check (now every 10th frame, still immediate on backing-store change), and the core 60 Hz HUD clock rewriting `textContent` on every tick (now write-on-change, ~1/s). The dominant residual — steady `getParameters` shader-program re-resolution (~4% of throttled main thread) — turned out to be Three r158+'s transparent-DoubleSide two-pass rendering, which sets `material.needsUpdate` twice per object per frame; all 18 of the 3D highway's transparent DoubleSide materials are flat unlit quads (labels, rails, chord frames, lanes), so they now declare `forceSinglePass: true`, eliminating the recompile churn and halving those objects' draw calls.

### Added
|
||||
- **3D Keys Highway: audio-reactive background ambience + score effects (parity slice 4 — completes the keys side of the visual-parity epic).** The gradient sky behind the highway gains the guitar's **background ambience styles** — drifting **Particles**, pitch-class-colored pulsing **Stage lights**, wireframe **Geometric** shapes, or Off — driven by the shared audio-analyser bridge (stems-first on sloppaks, one-shot `#audio` fallback; bass/mid/treble bands, 5 ms cache) with an **Ambience intensity** slider and an **Audio-reactive** toggle. And the score talks back: a **score-FX overlay** canvas draws rising **“+1” pops** off each scored key, an **expanding ring every 10-combo tier**, **milestone bursts** at 25/50/100 streak, and a brief **red flicker** when a 3+ streak breaks (wrong notes and swept misses both count). All settings-gated and on by default (`keys3d_bg_*`), pooled, cleared when idle, torn down with the scene. Butterchurn/image/video remain out of scope. The `#audio` analyser tap is also **shared across visualizers** now (`window.__feedBackAudioTap` — whoever taps first publishes, everyone else adopts, `highway_3d` included), so switching between or splitting the guitar/drum/keys highways can't strand a permanently non-reactive backdrop, and the tap is never created before the page has user activation (a suspended AudioContext would silence live playback). Tests: bg-style id validation + FX defaults (30 total).
|
||||
- **3D Keys Highway: the anti-plastic pass — lacquered note gems, glossy piano-black keys, a studio environment, scene themes and a gradient sky (parity slice 3).** The note gems move to `MeshPhysicalMaterial` with a full **clearcoat** (roughness 0.32, clearcoat 1.0/0.18, envMapIntensity 0.9): a sharp lacquer highlight over the colored body instead of the old dead matte surface — glass, not plastic. What sells it is **image-based lighting**: the same procedural PMREM "studio" environment as the drum highway (dark room + cool overhead / warm+cool side light strips, no addon dependency) feeds `scene.environment`, so the **black keys finally read as glossy piano black** (roughness 0.55 → 0.22, envMapIntensity 1.3) with visible strip reflections, whites keep an ivory sheen (0.42/0.55), and the highway floor gets a stage sheen (roughness 0.9 → 0.55, metalness 0.15). The flat background becomes a **vertical gradient** (lighter above the horizon → theme color → darker toward the keyboard), and the guitar highway's **11 scene themes** arrive (same names/values — your look carries across instruments; `default` preserves the original keys palette; pitch-class note/key colors are never themed — themes own the scene, Synthesia colors own the notes). Plus **Cinematic lighting** (ambient 0.55/key 1.3, on by default) and a **Glow strength** slider multiplying the note glow, key approach-glow and the sustain consume-flash (0.5 = stock). All live-applying from the Graphics settings (`keys3d_bg_theme` + `keys3d_bg_*`); the PMREM target and gradient texture are disposed with the scene. Tests: theme-table id parity + default-look preservation + fallbacks (28 total).
|
||||
- **3D Drum Highway: audio-reactive background ambience + score effects (parity slice 4 — completes the drum side of the visual-parity epic).** The empty fog band behind the kit gains the guitar highway's **background ambience styles**: drifting **Particles**, palette-colored pulsing **Stage lights**, and slowly-tumbling wireframe **Geometric** shapes (plus Off) — driven by the same audio-analyser bridge the guitar uses (prefers the stems plugin's per-song analyser on sloppaks, falls back to a one-shot `#audio` tap; bass/mid/treble bands with a 5 ms cache), with an **Ambience intensity** slider and an **Audio-reactive** toggle (off = the styles animate on time only; a permanently-tapped `#audio` in a mixed split degrades the same way). The guitar's butterchurn/image/video styles are deliberately out of scope (vendored megabytes / upload plumbing; the style enum is extensible). And your combo finally talks back: a **score-FX overlay** (2D canvas over the WebGL scene, guitar `drawScoreFx` adapted to this plugin's internal scoring) draws rising **“+1” pops** off each scored lane, an **expanding ring pulse every 10-combo tier**, **milestone particle bursts** at 25/50/100 streak, and a brief **red flicker** when a 3+ streak breaks. Everything is settings-gated (Background ambience dropdown + intensity + reactive, Score effects toggle — all on by default, live-applying, `drum_h3d_bg_*` keys), pooled (zero per-frame allocation), and torn down with the scene across kit changes. Tests: bg-style id validation + FX defaults (15 total).
|
||||
- **3D Drum Highway: real materials + scene themes (parity slice 3).** The scene gets **image-based lighting**: a procedural PMREM "studio" environment (dark room + three emissive light strips — cool overhead key, warm/cool side fills; no vendored-addon dependency) feeds `scene.environment`, so the cymbals' metalness **finally reads as metal** (retuned to roughness 0.2 / metalness 0.85 / envMapIntensity 1.2 — the old 0.7-metalness look was matte because there was nothing to reflect), drumheads get a satin sheen, and the floor (roughness 0.95 → 0.7) catches the strips without turning into a mirror. **Scene themes arrive** — the same 11 theme names as the guitar highway (Midnight, Charcoal, Deep Purple, Forest, Warm Slate, Deep Focus, Deep Sea, Cathode, Cathode Green, Hearth) retint the background/fog, floor and lane stripes so your look carries across instruments; `default` preserves the original drum palette byte-for-byte, and piece colours stay with the existing Palette picker (themes own the scene, palettes own the kit). Plus **Cinematic lighting** (dimmer ambient / stronger key, on by default), a **Glow strength** slider (0–1, 0.5 = stock) multiplying every emissive base — notes, hit line, snare wires — and a **Lane vibrancy** slider driving stripe/halo/ghost-ring strength (the hit-FX approach highlight stacks on top). Everything applies live from the plugin settings (`drum_h3d_bg_theme` + `drum_h3d_bg_*` keys); the PMREM render target is rebuilt across kit-change renderer recreation and disposed in both teardown paths — and the floor/hit-bar geometry+materials that previously leaked on every kit change are now tracked and disposed too. Tests: theme-table parity with the guitar ids + default-look preservation + fallbacks (13 total).
