* feat(highway_3d): add Butterchurn visualizer background style Adds an opt-in "Butterchurn (visualizer)" option to the 3D Highway plugin's Background-style dropdown. When selected, the highway renders over a WebGL MilkDrop (Butterchurn) canvas that reacts to your playing (guitar input on desktop, the song <audio> spectrum in the browser) and the chart (beat/note/ chord accents + instrument-color tint). The default stays 'particles', so existing users see no change until they pick it. Integrates the standalone "3D Highway + Butterchurn" mod into the bundled renderer as the 'butterchurn' bg-style (not a fork): - a self-contained _bc* controller that lazy-loads the vendored butterchurn libs only when the style is selected; mount/unmount is driven idempotently by the existing bg-style lifecycle (_bcSyncMode in _bgMountStyle) plus an explicit teardown in destroy() - the renderer uses alpha:true with the transparent clear gated on the mode, so every other bg style stays byte-identical (opaque clear) - the fog-scenery <audio> tap is disabled while active to avoid a double createMediaElementSource on #audio - the mod's slopsmith* globals are adapted to the current feedBack* names and the vendored asset URLs repointed to /api/plugins/highway_3d/assets/ Vendors butterchurn.min.js + butterchurnPresets.min.js (MIT) + viz-worklet.js under assets/vendor/; see plugins/highway_3d/NOTICE for attribution.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011Q9BpGYqUaga9ZJyS3dDPq * fix(highway_3d): harden Butterchurn audio + lifecycle (review #597) Browser audio reactivity now REUSES the highway's existing shared analyser (the fog scenery's #audio / stems side-chain tap) instead of opening a second createMediaElementSource on #audio. The old _bcBrowserSource path: - threw InvalidStateError when the fog tap already owned #audio (default config), leaving the visualizer non-reactive in the browser, and could permanently disable fog reactivity if it tapped first (one-shot/element); - rerouted the song through a fresh, possibly-suspended AudioContext, which could MUTE playback when butterchurn was selected mid-song; - ignored the stems analyser, so it saw only silence on sloppak songs. _bcCreateController now takes an audioProvider (wired to _bgGetAnalyser) and connectAudio()s the shared AnalyserNode (a passthrough, so the fog's own reads are undisturbed). Also: - destroy() now closes the AudioContext when we own it (desktop / browser fallback), fixing a per-mount leak that hit the browser ~6-context cap after a few style toggles. The shared (fog-owned) context is never closed. - _bgApplyVenueSceneFog keeps the clear transparent while butterchurn is active, so the venue scene no longer occludes the visualizer. - _bcLoadLib no longer caches a rejected promise, so a transient vendor-load failure can be retried instead of disabling the feature for the session. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(highway_3d): Butterchurn lifecycle + audio re-bind (Codex preflight) Local Codex preflight on the Butterchurn feature flagged four issues; all fixed: - WebGL context leak on teardown: destroy() (and the async-init failure path) now call _bcReleaseCanvasGL() to force WEBGL_lose_context before dropping the canvas, so repeated mount/toggle cycles can't exhaust the browser's WebGL context cap. - Stale shared analyser across songs: the browser path captured the analyser once at mount, so a sloppak stems swap (new analyser, often new context) left the visualizer reacting to a dead node. update() now compares the live _bgGetAnalyser() against what the controller actually bound (boundAnalyser(), guarded by ready()) and either reconnects (same context) or rebuilds the controller (context changed) via the proven destroy()+_bcSyncMode paths. - Half-mounted controller on createVisualizer failure: the async .catch now cleans up (closes an owned AudioContext, removes layers, marks dead) and _bcSyncMode retries when bcCtrl.dead(), instead of leaking and never recovering. - _bcFfIdx off-by-one dropped accents landing exactly on a seek/loop target time; it now uses strict < so the update walkers fire the boundary event.
