🎯 MapView v2.0 - Global Deployment Ready

✨ MAJOR FEATURES:
• Auto-zoom intelligence với smart bounds fitting
• Enhanced 3D GPS markers với pulsing effects
• Professional route display với 6-layer rendering
• Status-based parking icons với availability indicators
• Production-ready build optimizations

🗺️ AUTO-ZOOM FEATURES:
• Smart bounds fitting cho GPS + selected parking
• Adaptive padding (50px) cho visual balance
• Max zoom control (level 16) để tránh quá gần
• Dynamic centering khi không có selection

🎨 ENHANCED VISUALS:
• 3D GPS marker với multi-layer pulse effects
• Advanced parking icons với status colors
• Selection highlighting với animation
• Dimming system cho non-selected items

🛣️ ROUTE SYSTEM:
• OpenRouteService API integration
• Multi-layer route rendering (glow, shadow, main, animated)
• Real-time distance & duration calculation
• Visual route info trong popup

📱 PRODUCTION READY:
• SSR safe với dynamic imports
• Build errors resolved
• Global deployment via Vercel
• Optimized performance

🌍 DEPLOYMENT:
• Vercel: https://whatever-ctk2auuxr-phong12hexdockworks-projects.vercel.app
• Bundle size: 22.8 kB optimized
• Global CDN distribution
• HTTPS enabled

💾 VERSION CONTROL:
• MapView-v2.0.tsx backup created
• MAPVIEW_VERSIONS.md documentation
• Full version history tracking
