v1.2.1

Features

• Synced (timestamped) lyrics — lyrics highlight and auto-scroll with the song in real time
• Click-to-seek on lyrics — click any synced lyric line to jump to that part of the song
• LRCLIB.net fallback — when YouTube Music doesn't provide synced lyrics, fetches them from LRCLIB.net (no API key needed)
• Lyrics auto-center — current lyric line stays centered in the viewport as the song plays

Bug Fixes

• Fixed crash on song change with both sidebars open — Textual's LoadingIndicator timer raced with widget pruning during track transitions
• Fixed crash from unhandled exceptions in player event callbacks — sync callbacks dispatched via call_soon_threadsafe now wrapped in error handlers
• Wrapped notify() and _prefetch_next_track() in _on_track_change with try/except to prevent crashes during app transitions
• Lyrics sidebar always starts closed on launch regardless of previous session state
• Fixed synced lyrics not being requested — timestamps=True now passed to ytmusicapi with automatic fallback to plain text
