// 3. Set up your backend endpoint (see STRIPE-BACKEND-SETUP.md)
// 4. Set PAYMENT_MODE to 'live' when ready for production

  // ===========================================
  // PAYMENT MODE CONFIGURATION
  // ===========================================
  // Options: 'demo' | 'test' | 'live'
  // - 'demo': Uses sandbox mode, no real payments (for UI testing)
  // - 'test': Uses Stripe test mode (for integration testing)
  // - 'live': Uses Stripe live mode (for production)
  PAYMENT_MODE: 'demo',

  // ===========================================
  // STRIPE API KEYS
  // ===========================================
  // Get keys from: https://dashboard.stripe.com/apikeys
  // 
  // TEST MODE KEYS (start with pk_test_ and sk_test_)
  // - Safe for development and testing
  // - Use test card numbers (e.g., 4242 4242 4242 4242)
  //
  // LIVE MODE KEYS (start with pk_live_ and sk_live_)
  // - Process real payments with real money
  // - Only use after thorough testing
  
  STRIPE_KEYS: {

  // ===========================================
  // BACKEND API CONFIGURATION
  // ===========================================
  // The endpoint that creates Stripe Checkout Sessions
  // Options for hosting:
  // - AWS Lambda + API Gateway (recommended for static sites)
  // - Vercel Serverless Functions
  // - Node.js/Express server
  // - Any backend that can call Stripe API
  
  // AWS API Gateway URL - from config.aws.js (single source)
