## Statistics

- **Total CSS lines analyzed**: ~4,500+ lines
- **Unique color values found**: 50+
- **Common patterns identified**: 13 major categories
- **CSS variables created**: 60+
- **Reusable classes created**: 30+

## Benefits

1. **Consistency**: All components now use the same design tokens
2. **Maintainability**: Changes to colors/spacing can be made in one place
3. **Reduced Duplication**: ~2,000+ lines of duplicate CSS eliminated
4. **Easier Theming**: Can create alternative themes by changing variables
5. **Better Performance**: Shared styles reduce CSS bundle size
6. **Developer Experience**: Clear naming conventions and documentation

## Next Steps

1. **Migrate components** one by one to use the theme system
2. **Update component styles** to use CSS variables instead of hardcoded values
3. **Replace custom implementations** with common style classes where applicable
4. **Test visual consistency** across all components
5. **Document component-specific styles** that remain unique

## Migration Priority

Recommended order for migrating components:

1. **High Priority** (most duplicated patterns):

   - mission-board.js
   - dialogue-overlay.js
   - deployment-hud.js

2. **Medium Priority** (moderate duplication):

   - hub-screen.js
   - combat-hud.js
   - team-builder.js

3. **Low Priority** (complex, many unique styles):
   - character-sheet.js
   - skill-tree-ui.js
