This ensures polling happens exactly every 500ms regardless of execution time. +- **Polling activation:** Only poll when isPlaying=true to avoid unnecessary jamClient calls when paused/stopped. This reduces CPU usage and native client overhead. +- **Error handling strategy:** Log errors to console but continue polling. This prevents transient jamClient failures from crashing the UI while still providing visibility. +- **Immediate duration fetch:** Fetch duration on track load (before play) so users see total length immediately, matching legacy web UI behavior. + +## Deviations from Plan + +None - plan executed exactly as written. + +## Issues Encountered + +None - straightforward implementation matching legacy web pattern. + +## Next Phase Readiness + +Phase 2 (Backing Track Seek Controls) can now proceed.
