## 🔥 Firebase Integration

This template comes pre-configured with Firebase services:

### Authentication
- Email/Password authentication
- Google Sign-In (configurable)
- Protected routes and user session management
- Authentication state persistence

### Firestore Database
- Real-time database operations
- Type-safe document operations
- Collection and subcollection support
- Optimistic UI updates

### Storage (Optional)
- File upload capabilities
- Image optimization
- Secure file access rules

### Configuration
All Firebase services are configured in `src/lib/firebase.tsx`. The template uses environment variables for secure configuration management.

## 🎨 Theme System

Built-in theme support with three modes:

- **🌞 Light Mode**: Clean, bright interface
- **🌙 Dark Mode**: Easy on the eyes for night coding
- **⚙️ System Mode**: Automatically follows OS preference
- **💾 Persistent**: Saves user preference in localStorage

### Usage Example

```tsx
import { useTheme } from '@/context/ThemeContext';

export default function ThemeButton() {
  const { theme, toggleTheme } = useTheme();
  
  return (
    <button 
      onClick={() => toggleTheme(theme === 'dark' ? 'light' : 'dark')}
      className="p-2 rounded-lg bg-gray-200 dark:bg-gray-800"
    >
      {theme === 'dark' ? '🌞' : '🌙'}
    </button>
  );
}
```
