In a real app, lazy-load this modal so it only loads when clicked - reducing initial bundle size.

✅ Best Practices

  • ✓Use sized fallbacks to prevent layout shift
  • ✓Lazy-load below-the-fold components
  • ✓Conditionally load modals and overlays
  • ✗Don't lazy-load above-the-fold content
  • ✗Don't use empty fallbacks (causes layout shift)
