+ * ===================================================
+ * Corporate-Grade JavaScript Architecture
+ * 
+ * @version 3.0.0
+ * @author Valentine Experience Team
+ * @license MIT
+ * 
+ * Architecture:
+ * - Modular ES6+ design with strict separation of concerns
+ * - Event delegation for optimal performance
+ * - Memory-safe event listener management
+ * - Hardware-accelerated animations (transform/opacity only)
+ * - Passive event listeners for scroll performance
+ * - WCAG 2.1 AA compliant interactions
+ * - Comprehensive error handling and fallbacks
+ * - Performance monitoring and optimization
+ * 
+ * Features:
+ * - Envelope opening animation with GPU acceleration
+ * - Touch-optimized drag system with passive listeners
+ * - Intelligent Z-index stacking management
+ * - Adaptive "No" button evasion algorithm
+ * - Progressive "Yes" button growth mechanics
+ * - Canvas-based particle system with RAF optimization
+ * - Cross-browser compatibility (Safari, Chrome, Firefox, Edge)
+ * - Memory leak prevention with proper cleanup
+ * - Graceful degradation for older browsers
+ * 
+ * Browser Support:
+ * - Chrome 90+
+ * - Firefox 88+
+ * - Safari 14+
+ * - Edge 90+
+ * - iOS Safari 14+
