A ladder is a hue walk, not a brightness walk, so painting the hot end
backwards put the dim colour at the corner. Sort the ramp by stock
brightness and follow the pane height for the bottom-left glow.
Registry lookup and its fallback for a stale slug, SomaFM branding and guessed mirrors, provider round-trip in the config, legacy-config migration and BEEFY_*/SOMAFM_* precedence - plus an end-to-end boot against a fake second provider, which is what actually proves the UI no longer knows about SomaFM.
The app now holds one RadioProvider and asks it for stations, song history and stream URLs instead of importing SomaFM's HTTP client directly.
- models.py: provider-neutral Song/Station plus the shared parsers every catalogue needs (Station.provider/.uid keep ids unique once there is more than one).
- providers/base.py: the RadioProvider interface and the toolkit it needs in practice - httpx client factory, .pls/.m3u resolution with an 8h disk cache, and a default stream_candidates() strategy.
- providers/somafm/: everything SomaFM-specific (channels.json, songs/<id>.json, PLS layout, guessed icecast mirrors) behind SomaFMProvider.
- providers/__init__.py: registry, get_provider() and --provider, remembered in the config file.
Widgets render branding, splash copy and the help credits from the active provider, so a second catalogue needs no UI changes; with SomaFM selected the screen is byte-identical to before.
The app is now a general internet-radio player rather than a SomaFM client, so the package, console script, MPRIS identity, mpv namespaces, macOS tap names, XDG directories and docs all move to beefy-player.
Environment variables are now BEEFY_* (the old SOMAFM_* spellings are still honoured) and an existing ~/.config/somafm-tui/config.json is migrated on first run, so favourites and volume survive the rename.
The visible interface is untouched: same layout, same logo, same keys.
