 Implement exactly these behaviors:

+Rooms (ui_page_rooms.*)
 
-Cards: tap → expand; long-press Quick Action → confirm sheet.
+- Grid of room cards populated from `ui_rooms_model.*`.
+- Tap the toggle on a card to fire `UI_PAGE_ROOMS_EVENT_TOGGLE` with optimistic feedback.
+- Long-press a card body to request the per-room sheet via `UI_PAGE_ROOMS_EVENT_OPEN_SHEET`.
+- Cards surface temperature/humidity badges and availability state.
 
-Status chips: navigate to relevant screen; anomaly colors: accent/warn/alert.
+CCTV (ui_page_cctv.*)
 
-Rooms
+- Primary camera card with Prev/Next controls, quality picker, and mute toggle shell.
+- Live feed placeholder sized per spec; keep toggles hidden on camera/event cards.
+- Event cards list recent clips; tapping should emit an open-clip signal when bindings arrive.
 
-List left, detail right; two-finger swipe changes room.
+Weather (ui_page_weather.*)
 
-Long-press a light → per-entity detail sheet.
+- Living Room card shows indoor temperature, humidity, and HVAC mode metrics.
+- Outdoor card surfaces raw sensor IDs with current readings.
+- Forecast row presents 3 quick-glance day summaries with iconography.
 
-Security
+Media (ui_page_media.*)
 
-Camera carousel + Live tile; event chips open clip/PiP.
+- Now Playing card renders album art, metadata, transport buttons, and a volume slider.
+- Quick Scenes card exposes preset buttons for lighting/media moods.
+- Hide unused default room-card specs/toggles when not applicable.
 
-Alert mode: frame screen in warn/alert, focus automatically.
+Settings (ui_page_settings.*)
 
-Control Center
-
-Swipe-down to open; brightness, volume, toggles; sleep action.
+- Connectivity testers display pill states (Online/Degraded/Offline) per status callbacks.
+- Theme block combines dark-mode switch and theme dropdown; changes propagate via async payloads.

+- Build the room card grid with `ui_room_card` widgets and wire toggle/long-press events.
+- Populate cards from `ui_rooms_model.*`; surface climate badges and availability state.
 
-Shared Card, Chip, Slider, Toast, Tabs, Confirm Sheet—styled via ui_theme.h.

+- Compose the live camera card with toolbar controls and video placeholder.
+- Lay out event cards for recent clips; stub tap handlers for future bindings.
 
-Wire Home card values to mock data → then swap to MQTT/Frigate bindings.
+Weather iteration
 
-Motion & feedback
+- Add Living Room and Outdoor cards with metric stacks.
+- Render the forecast row with icon + high/low pairs.

+Media iteration
 
-Add expand/contract, color pulse, toast confirmations; error states.
+- Flesh out the Now Playing card (album art, metadata, transport controls, volume slider).
+- Add Quick Scenes buttons and make them emit scene selection events.

+Settings iteration

+- Implement connectivity testers, theme toggle/dropdown, brightness slider, and action buttons.
+- Expose async setters for status/theme/brightness updates.

+Motion & feedback
