Added staleness check timer (1s interval) to SpeedometerScreen + - Speed/heading displays dim at 3s, show dashes at 10s (identical to overlay) + - Staleness calculated from `ProcessedGpsData.timestamp` field + - Applied to both speed and heading displays in portrait and landscape layouts + - Timer properly canceled in dispose() + +2. **Wake Lock Management Centralized** + - Removed `wakelock_plus` import from SpeedometerScreen + - Removed `_enableWakelock()` method entirely + - Removed `WakelockPlus.disable()` from dispose() + - Wake lock now exclusively managed by GpsDataManager (Task 04-01) + +3. **Lifecycle Management Centralized** + - Removed `WidgetsBindingObserver` mixin from SpeedometerScreen + - Removed `didChangeAppLifecycleState()` override + - Removed `_isInBackground` field and `_handleBackgroundTransition()` method + - Removed `_requestBatteryOptimizationExemption()` stub + - Lifecycle awareness now exclusively in GpsDataManager (Task 04-01) + +4. **Simplified Background Heartbeat** + - Removed `_isInBackground` check from heartbeat logic + - Heartbeat now simply checks `overlay.isOverlayActive` and pushes data + - Cleaner logic without redundant state tracking + +5. **Provider Wiring Completed** + - Added `gpsDataManager.setOverlayProvider(overlayProvider)` call in initState + - Enables GpsDataManager to check overlay state for background GPS decisions + - No circular dependencies (wired after both providers available) + +6. **OverlayProvider Cleanup** + - Removed `_gracePeriodTimer` field + - Removed all grace period logic from `showOverlay()` and `_handleOverlayClose()` + - Removed grace period cancel from dispose() + - Grace period management now handled by GpsDataManager's background lifecycle + +7. **Enhanced User Experience** + - Added haptic feedback to theme cycling (speed display tap) + - Added haptic feedback to unit cycling (unit label tap) + - Consistent tactile response across all main UI interactions + +8. **Speed Display Opacity Support** + - Updated `_buildSpeedDisplay()` to accept opacity parameter + - Applied staleness opacity to integral and decimal parts + - Applied staleness opacity to dash display ("--") + +9. **TimingConfig Status** + - `GPS_GRACE_PERIOD` (30s) remains in TimingConfig with deprecation comment + -
