Notes

Performance Optimizations

• Schedule view caches for 30 seconds
• Analytics caches for 60 seconds
• Widget data cached by browser
• Bulk queries for multiple schedules

Security Considerations

• All endpoints validate input
• No authentication required for public views (by design)
• Widget uses shadow DOM for style encapsulation
• API endpoints have rate limiting (via CDN/server)

Browser Compatibility

• Widget uses standard Web Components API
• Fallbacks for older browsers via public /widget.js
• All pages use modern CSS (grid, flexbox)
• TypeScript ensures type safety

Accessibility

• Semantic HTML structure
• ARIA labels where needed
• Keyboard navigation support
• High contrast dark mode
