feat(spotify): fetch synced lyrics from color-lyrics endpoint#369tharinfernando wants to merge 2 commits into
Conversation
Add synced lyrics for Spotify tracks via the internal color-lyrics endpoint, falling back to LRCLIB/NetEase. Add a persisted lyric timing offset ([ / ] in the lyrics overlay, lyrics_offset_ms) to correct tracks whose timestamps drift from the audio master.
📝 WalkthroughWalkthroughThe change adds Spotify synced-lyrics retrieval, persistent lyric timestamp offsets, keyboard controls for offset adjustment, configuration support, tests, and documentation updates. ChangesLyrics synchronization
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds Spotify synced-lyrics fetching and persistent timing controls, but offset controls can still affect unsupported lyric modes and a failed save can appear successful to the user. The change is mergeable with explicit owner awareness or follow-up for these bounded configuration and UX issues. Sequence Diagram(s)sequenceDiagram

Use HTML key markup and document persistence.
The backticks render literally in this HTML page. Use <kbd> elements for [ and ]. State that the timing adjustment persists as lyrics_offset_ms so the site matches the documented config behavior.
As per coding guidelines, keep docs/ and site/index.html in sync on user-visible keybindings, providers, and config keys.

Gate offset updates in the key handler.
commandRegistry hides these controls for unsyncable or untimestamped lyrics, but handleKey still persists lyrics_offset_ms for every lyrics overlay. This can change later synced-lyrics highlighting after a user presses [ or ] on plain lyrics or a stream.
Require m.lyricsSyncable() && m.lyricsHaveTimestamps() before calling nudgeLyricsOffset.

Preserve the configuration save error.
If configSaver.Save fails, Errorf sets the error status, but the following Warningf overwrites it in the same statusMsg. Return after Errorf, or show the warning only after a successful save.
