🌐 FRONTEND INTEGRATION (JavaScript/TypeScript):

import { invoke } from '@tauri-apps/api/tauri';

// Initialize camera system
await invoke('initialize_camera_system');

// Get available cameras  
const cameras = await invoke('get_available_cameras');
console.log('Available cameras:', cameras);

// Get platform-optimized format
const format = await invoke('get_recommended_format');
console.log('Recommended format:', format);

// Capture single photo
const photo = await invoke('capture_single_photo', {
  deviceId: cameras[0].id,
  format: format
});
