- Sources: "free" (Creative Commons songs with media from
github.com/UltraStar-Deluxe/songs) and "usdb" (usdb.animux.de with an
account; audio/video via yt-dlp from the song's #VIDEO hints or YouTube
links in the comments, covers from fanart.tv/YouTube)
- Aggregated search (all sources in parallel, in-library flag), download
queue into <library>/Downloads/<source>/<Artist - Title>, then rescan
- Web UI in wwwroot (plain JS, no build): search, downloads with progress,
library; phone first, dark mode, installable
- Docker image with yt-dlp, ffmpeg and deno; library mounted writable
- Tests for matching, USDB parsing and song rewriting
