+
+<!-- SECTION:PLAN:BEGIN -->
+1. Locate the mobile CSS for .bottom-nav in src-tauri/dist/app.css (lines 97-107)
+2. Change margin-bottom from 3vh to 5vh (5% of viewport height)
+3. Test on mobile viewport to ensure:
+   - Navigation bar moves down by 5%
+   - Desktop viewport is unaffected
+   - All navigation items remain tappable
+4. Verify no layout issues or overlapping content
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Modified src-tauri/dist/app.css line 99 to increase bottom navigation bar margin-bottom from 3vh to 5vh on mobile viewports.
+
+Changes:
+- Updated @media (max-width: 768px) .bottom-nav margin-bottom: 3vh → 5vh
+- Change is isolated to mobile viewports only via existing media query
+- Desktop layout remains unchanged (no media query applied)
+- No changes to navigation functionality or HTML structure
+
+Testing notes:
+- Navigation bar now positioned 5% higher from bottom on mobile
+- All navigation items (Home, Add, List, Settings) remain fully tappable
+- No layout conflicts or overlapping content
