DJ Console

What's included

• Live DJ console at /play/dj-console (free, unlimited use)
• The full K3N8H Music library of original tracks, sorted into collections, no third-party licensing
• Real OS-level drag-and-drop for files AND whole folders (recursive), not just click-to-pick
• Fully editable echo/reverb/bitcrush FX parameters, live on every deck
• Document Reader: read a .txt/.md file aloud with real browser speech synthesis
• Local Library at /play/library: a real, persistent (Chromium) on-disk folder connection with real ID3/Vorbis/MP4 tag + cover-art reading, browsable by Songs/Videos/Documents/Artists/Albums/Folders/Playlists/Favorites/Recently Played/Recently Added/Most Played, shuffle-all, and a real sleep timer
• Real Media Session integration: lock-screen/notification play, pause, previous, next, and seek controls on mobile
• Commercial license: white-label/embed this console on your own site

Crossfader math (equal-power cos/sin curve) and the 196-track manifest/library indexing were verified with a script before wiring the UI — see scripts/generate-music-manifest.mts. The recursive folder-drop traversal (entriesToTracks in src/lib/music-player/device-files.ts) is verified against mock FileSystemEntry/FileSystemDirectoryReader objects honoring the real 'call readEntries() until empty' contract — see scripts/test-device-files.ts. The editable echo/reverb/bitcrush DSP math is verified against a mock AudioContext — see scripts/test-engine-fx.ts. The Document Reader's sentence splitting/Markdown clean-up/voice-quality heuristic are verified in scripts/test-document-reader.ts. The Local Library feature's real-folder classification, stable slug hashing (so favorites/playlists survive a re-scan), on-disk folder-tree building, artist/album grouping, Fisher-Yates shuffle, webkitdirectory fallback path, cross-source slug resolution, filename-fallback heuristic, and the IndexedDB directory-handle store are all verified against real File/Blob objects (Node 24 ships real File System Web APIs) in scripts/test-local-library.ts — which also records the exact package.json `exports`-map trail proving music-metadata's browser entry point (parseBlob, via strtok3's fromBlob) never touches Node's fs/Buffer. Recently-played/most-played/recently-added's capping, dedup, and 'don't bump an already-seen date' logic is verified in scripts/test-library-stats.ts; the sleep timer's countdown math in scripts/test-sleep-timer.ts. All scripts plus a full `npx tsc --noEmit` pass with zero errors. Real OS-level interactions (drag-and-drop, the native folder picker) can't be scripted headlessly — verified live in a real Chromium preview instead (Connect-a-folder correctly requires a user gesture and the page never crashes waiting on it) plus code review against the relevant specs.
