 **Styling Approach**: Implements Tailwind CSS for utility-first styling with custom CSS variables for theming. The design system supports automatic dark/light mode switching and maintains consistent spacing using Tailwind's spacing units.
 
+**Internationalization**: Implements i18next and react-i18next for multilingual support. Currently supports English (default) and German translations. Language preference is stored in localStorage and persists across sessions. Translation files are organized in JSON format at `client/src/i18n/locales/`.

 **Mobile-First Responsive Design**: The interface is fully optimized for mobile devices with adaptive layouts that efficiently use screen space across all viewport sizes:
 - **Responsive Container**: Main layout uses responsive padding (px-3/py-4 on mobile, px-4/py-6 on desktop) with max-w-screen-2xl constraint to prevent excessive horizontal spread on large screens
 - **Calendar Grid Breakpoints**: Adapts from 2 columns on mobile (375px), to 3 columns on small tablets (640px), 5 columns on tablets (768px), and full 7-column week view on desktop (1024px+)
