 **State flow**: `MatrixSession` owns a `syncState: StateFlow<SyncState>` that all screens observe. The background sync loop continuously updates it via `/sync` long-polling.
 
-## Push notifications
-
-When the app is in the foreground or background, notifications are fired directly from the sync loop. When the app is killed, push is delivered via FCM through a self-hosted Cloudflare Worker (`gateway/`) that acts as a Matrix push gateway.

 ## Known limitations
 
+- No E2E encryption (plain-text transport only; suitable for unencrypted rooms)
+- No push notifications
 - No media/file messages (text only)
 - Room list is not paginated (loads whatever `/sync` returns on first sync)
