faster load with React + code splitting + image optimization
JSON-LD Schema

Checking for schema blocks on this page...

What improves in the React build (all else equal):
  • Code splitting — only the current page's JS is loaded
  • Image optimization — WebP conversion + lazy loading via React Image
  • CDN caching of static assets via Vercel/Netlify edge network
  • Tree-shaking removes unused CSS and JS from the bundle
  • Prefetching — next pages load before the user clicks

Developer note: Remove this banner and modal entirely from the React production build.
