This document outlines the migration of the Altarra app from Tailwind CSS to Material-UI (MUI).

  - Custom typography and component overrides

### 2. Layout

## Styling Approach

All components now use MUI's `sx` prop system, which provides:
- Type-safe styling
- Direct access to theme values
- Responsive design support
- Better performance

## Migration Benefits

1. **Consistency**: Unified design system across the app
2. **Accessibility**: Better built-in a11y features
3. **Theming**: Centralized theme management
4. **Components**: Rich set of pre-built components
5. **Developer Experience**: Better TypeScript support and IDE integration

## Notes

- Tailwind CSS configuration can be safely removed if no longer needed
- The app maintains the same visual appearance and functionality
- All forms and interactive elements work as before
- Language switching is preserved
- Responsive design is maintained through MUI's breakpoint system
