+[2026-01-10 20:45] MONICA SESSION: UI Refinements & Polish
+- Changes Applied:
+  * Centered all main containers (body: flex items-center justify-center)
+  * Reduced card spacing dramatically for compact dense layout
+    - Grid gap: gap-5 → gap-2 (between cards)
+    - Card padding: p-5 sm:p-6 → px-2 py-0.5 (internal spacing)
+    - Internal spacing: space-y-3 → space-y-0 (elements in cards)
+  * Improved attachment indicator icons with outline strokes instead of fills
+    - Image: mountain/landscape icon (clearer than grid pattern)
+    - Video: play button with frame (recognizable)
+    - Audio: speaker icon (listening/playback, not microphone which is for recording)
+    - File: document with corner fold (standard file representation)
+  * Fixed mobile view icon visibility by increasing size to 24px and adding flex-shrink-0
+  * Replaced purple badges with subtle hover-on-gray style for icons
+- Result: Cleaner, more compact UI with better visual hierarchy
+- Status: Fixed and committed (a168fe2)

 [2026-01-10 20:10] MONICA SESSION: Fixed Container Injection Bug
 - Issue: Refactor commit (cee9157) had CONTAINERS + initializeContainers() code
   but ALSO kept all old HTML in DOM, creating duplicates and preventing injection
