   - [ ] Check all sections are readable

2. **Scrolling:**

   - [ ] Test heat grid horizontal scroll
   - [ ] Test team scores vertical scroll
   - [ ] Test team scores horizontal scroll
   - [ ] Test splits vertical scroll
   - [ ] Test splits horizontal scroll
   - [ ] Resize window to narrow, verify scrolling

3. **AppIcon:**
   - [ ] Follow `AppIcon_Setup_Instructions.md`
   - [ ] Add icon images
   - [ ] Clean build folder
   - [ ] Rebuild
   - [ ] Check Dock
   - [ ] Check Finder
   - [ ] Check ⌘-Tab switcher

### Edge Cases (5 minutes)
- [ ] Test with window at minimum size
- [ ] Test with Content Zoom at 250%

## 🐛 Known Issues to Watch For

### Dark Mode
- ⚠️ **Symptom:** Some custom colors don't adapt to dark mode
- **Fix:** Replace hard-coded colors with semantic colors (.primary, .secondary, etc.)
- **Status:** All existing colors use semantic values - should work correctly

### Scrolling
- ⚠️ **Symptom:** Content doesn't scroll horizontally
- **Possible cause:** Content width is less than panel width
- **Test:** Add very long names to force horizontal overflow
- **Status:** Minimum widths added to ensure scroll activation

### AppIcon
- ⚠️ **Symptom:** Icon doesn't appear after adding to assets
- **Fix:** Clean build folder, delete derived data, restart Xcode
- **Fix:** Reset macOS icon cache (see instructions)
- **Status:** Setup instructions include troubleshooting
