 Tapping a tab replaces the current screen with a subtle fade + slight horizontal nudge transition (220ms forward, 200ms reverse). The back button is suppressed on all three main screens — navigation between them is flat, not stacked. All icons use outline variants (`people_outline`, `tag`, `map_outlined`) following Material 3 conventions.
 
-## Device Screen
+## Disconnection
 
-The Device Screen is a transitional hub that shows after connection. In practice, the app navigates directly to Contacts after connecting, but the Device Screen is reachable via the QuickSwitchBar.

-### What the User Sees
-
-**App Bar**:
-- Left: Battery indicator chip (tappable — toggles between percentage and voltage display). Icon changes based on level: `battery_unknown` when data unavailable, `battery_alert` (orange) at 15% or below, `battery_full` otherwise
-- Left-aligned title (`centerTitle: false`): Two-line layout — small grey "MeshCore" label above the device name in bold
-- Right: Disconnect button (`bluetooth_disabled` crossed-out icon) and Settings button (tune icon)
-
-**Body**:
-- **Connection Card**: Device avatar, device name, device ID, "Connected" chip, and battery chip
-- **Quick Switch** section: The QuickSwitchBar widget for navigating to Contacts/Channels/Map

+- The disconnect button (available in the Settings screen and other main screens) shows a confirmation dialog before disconnecting
 - If the device disconnects unexpectedly, the app automatically navigates back to the Scanner screen (fires after the current frame completes via a post-frame callback)
 - This auto-navigation behavior (`DisconnectNavigationMixin`) is shared across all main screens
 
 ## Theme and Locale
 
 - **Theme mode** is user-configurable in App Settings (System / Light / Dark) — not locked to system
-- **Language** can be overridden to one of 15 supported languages, or follow the system locale
+- **Language** can be overridden to one of 18 supported languages, or follow the system locale
 - On web, if a non-Chromium browser is detected, the app shows a `ChromeRequiredScreen` instead of the Scanner (Web Bluetooth requires Chromium)
