🔋 Foreground Service (FOREGROUND_SERVICE) & Background Running
GarSync requires foreground service permissions (FOREGROUND_SERVICE) and uses these specific service types for user-initiated core features:
1. FOREGROUND_SERVICE_LOCATION: Maintains active background GPS tracking during outdoor workouts to prevent route loss when screen is locked.
2. FOREGROUND_SERVICE_HEALTH: Maintains background Bluetooth connections with external sensors (heart rate monitors, power meters) for AI Coach biometrics.
3. FOREGROUND_SERVICE_MEDIA_PLAYBACK: Plays ambient sleep sounds (rain, forest, ocean waves) in the background.
Services run only while feature is active, with a visible notification enabling user control and one-tap stopping.
