+

-### 🎨 UI Improvements
+### 🛠 Improvements
 
-* Updated room badges to include **LAN mode styling**.
-* Improved consistency of badge colors across IP, LAN, and paired/secret rooms.
+* Chat notifications are now properly handled by the `Notifications` service instead of being bound to the wrong UI class.
+* Notification triggering logic was standardized using `document.hidden` and `document.visibilityState`.
+* Improved visual feedback for **unread messages received while the chat popup is closed** (pinned highlight until reload).
+* Better UX consistency with existing notification patterns in the app.
 
-### 🛠️ Developer Experience
+### 🐛 Fixes
 
-* Improved translation structure to simplify future localization updates.
-* Minor cleanup in styles related to room badges.
+* Fixed an issue where chat notifications **did not fire** due to the handler being registered in the wrong class (`ChatUI` instead of `Notifications`).
+* Fixed cases where messages received while the chat popup was closed **were not rendered when reopening**.
 
-### 🐞 Fixes
+### 📁 Files Changed
 
-* Fixed mixed-language labels appearing in some UI sections.

+### 🧪 Testing
 
-### ⚠️ Known Limitations
+* Not executed (manual testing recommended):
 
-* LAN mode uses local signaling for WebRTC (no native device discovery due to browser limitations).
-* Full offline peer discovery is only available in native desktop builds (e.g., Electron).
+  * Reload the page (Ctrl + F5).
+  * Send a message from another device/tab.
+  * Keep the chat tab in background to verify browser notifications.
+  * Test image/video upload and rendering in chat.
