Lyrics and karaoke for the music player
build-container / build (push) Successful in 12m8s

- full-screen lyrics view that follows the song: highlighted current line with a colour sweep (word by word when the source has word timing), tap a line to jump, text size, timing nudge, 'Wrong lyrics?' search
- Karaoke mode: the current line large and centered
- lyrics from Plex first, then the bundled Lyrica service (LRCLIB, Musixmatch via Lrcmux, NetEase, Megalobiz); YouTube captions never used; wrong-length recordings refused; answers kept in /data/lyrics
- lyrica/: Lyrica pinned to one commit, built by the workflow as hub-lyrica; compose service sharing the hub's network
- tools/lyrics-test.js
