- Fixed ChartPlaceholder canvas rendering by replacing CSS variables with hardcoded colors
* Canvas context cannot use CSS variables; must use RGB/hex colors directly
* Now renders ship track, waypoints, heading indicator, and legends correctly
- Enhanced ZoneCard with connection indicators
* Added visual source badges (Spotify 🎵, AirPlay 🎙️, Mopidy 📻)
* Color-coded left border matching source (green for Spotify, blue for AirPlay, amber for Mopidy)
* Added source dropdown selector for switching audio sources
* Shows grouped zone info when zones are merged
- Implemented zone grouping system in ZoneGrid
* Left sidebar panel to view and manage active zone groups
* Click 🔗 button to create/remove zone groups
* When zones are grouped, changing source updates all members
* Each zone can show which other zones it's grouped with
- All 64 modules build successfully
- Mock data properly flows through Snapcast with Spotify/AirPlay/Mopidy sources
