- Rewrote MainScreen: top bar, prominent status hero (idle/clear/watching/alert), active vs trusted sections, per-tracker cards with status icons, and a detail bottom sheet with co-movement evidence + trust action.
- Sensitivity selector with per-mode explanation; on-device/no-network footer.
- core-ktx 1.13.1->1.15.0, activity-compose 1.9.3->1.10.1 (kept the proven Kotlin/AGP/Compose matrix for build stability).
