        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
```

### Using Nginx
```nginx
server {
    listen 80;
    server_name system.local;
    root /var/www/project;
    
    location ~\.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}
```

## 📊 Performance

- **Page Load:** < 3 seconds (on 10 Mbps connection)
- **API Response:** < 500ms for most endpoints
- **Map Rendering:** Real-time interactivity
- **Scoring Computation:** < 1 second for 100 households

## 🛠️ Development Guide

### Adding New Endpoint
1. Create new file in `/api/` folder: `your_endpoint.php`
2. Include `config.php` for database access
3. Use `requireLogin()` or `requireRole()` for access control
4. Return JSON response

Example:
```php
<?php
header('Content-Type: application/json');
require_once 'config.php';

requireRole(['Admin', 'Petugas']);

// Your code here

die(json_encode(['success' => true, 'data' => $result]));
?>
```

### Modifying Frontend
1. Edit `js/app.js` for logic changes
2. Edit `css/style.css` for styling
3. Edit `index.html` for structure/layout
4. Refresh browser to see changes (no build required)

## 🐛 Troubleshooting

### Login Issues
- Verify email: `admin@system.local`
- Verify password: `admin123`
- Check browser cookies are enabled
- Clear cache and try again

### Map Not Loading
- Check browser console for errors (F12)
- Verify internet connection (for Leaflet CDN)
- Try refreshing page

### Database Issues
- Ensure `/db/` folder has write permissions
- Check PHP error logs
- Delete `db/markers.db` to reset (will lose data)

### Performance Issues
- Check browser performance (F12 > Performance tab)
- Monitor server CPU/memory usage
- Consider adding pagination for large datasets
