- FirestoreQuestionThreadDataSource: sendImageMessage encrypts bytes with couple key, uploads to Storage, stores URL in Firestore; loadDecryptedMedia downloads + decrypts
- QuestionMessage: type field (text/image), mediaUrl, isImage helper
- QuestionDiscussionThread: image picker (gallery + camera), encrypted image rendering with produceState, messenger-style avatars on consecutive bubbles
- QuestionThreadViewModel: sendImage, loadDecryptedMedia, dailyRevealed skip for already-revealed daily questions, partner photo loading
- MainActivity: deepLinkRouteFromIntent resolves FCM data extras to navigation routes; pendingDeepLink state for onNewIntent
- AppNavigation: LaunchedEffect waits for HOME route before navigating deep link (fixes race with onboarding)
- PartnerHomeScreen: partner photoUrl loaded and displayed in identity card
- NotificationRateLimiter: 20 partner/day, 100/week (was 2/4 — too tight for game activity)

- MessageBubbleController/Overlay: new in-app chat-head that drifts over all screens, tap to open
- PartnerNotificationManager: GAME_RESULTS_READY type with proper copy, partner_finished_game maps to it
- onGameSessionUpdate: notify BOTH partners on completion (not just the non-starter), fix starter name in notification
- Firestore rules: partner can read user doc (name/photo), sender can read own release key
