Music persistence across scene switches by extracting playback into a
separate browser source (music/index.html) — single source instance
shared across scenes via OBS's "Add Existing", so it doesn't restart on
scene change.
Loading and Game overlays subscribe to mpd:state CustomEvents over OBS
WebSocket; the daemon broadcasts at 1 Hz plus on every track change.
File-based command pipeline lets bash control playback without a
WebSocket client of its own:
- vendor/obs-ws-mini.js — minimal WS v5 client with HMAC-SHA256 auth,
hard timeout, close-rejection, and a pure-JS SHA-256 fallback for
CEF file:// origins where crypto.subtle is unavailable.
- setup.sh — generates vendor/obs-config.js from the OBS plugin config;
checks the live socket instead of the (lagging) config file.
- music/index.html — invisible audio worker. Plays through a shuffled
queue with hardened error/stall recovery, polls loading/cmd.js for
bash-issued commands, broadcasts mpd:state via WS. Includes a
diagnostic status block (visible if the source's eye-icon is on).
- loading/index.html — strips local audio playback; subscribes to
mpd:state to drive the now-playing terminal line live. Removes the
redundant trailing prompt; terminal lines anchor at the bottom.
- loading/playlist.sh — rebuilt as subcommand API:
sync (default), skip, prev, pause, resume, status
control commands write loading/cmd.js (id, type, ts), which the
daemon polls every 250ms.
- loading/convert.sh — strips video tracks from .webm music downloads
to audio-only m4a (~95% smaller, ~20× faster decode); fixes the
CPU pegging from CEF decoding 1080p VP9 video for music playback.
- .gitignore — track manifests, ignore generated wrappers + secrets +
the audio cache.

# loading/convert.sh — strip video tracks out of audio files in

# WHY: yt-dlp .webm downloads include 1080p video. Chromium's <audio>
|
||
# element decodes the video stream too (just doesn't render it) — pegs
|

# CPU and stalls playback mid-track. Audio-only m4a is ~95% smaller
