Boost Lovable-Supabase Site

I’m preparing my Lovable + Supabase + stripe site for production and need it running fast and feeling smooth before I hit deploy. At the moment the bundle is heavier than it should be and a few UX rough spots remain.

What I’m after is a focused round of optimisation that:

• Cuts load times noticeably through smart code splitting, aggressive caching, and tidy minification
• Delivers crisp, properly sized images with modern formats and lazy-loading where appropriate
• Polishes the navigation flow so users always know where they are and how to get where they’re going
• Makes every screen fully responsive—from the smallest phones up—without layout quirks
• Brings the interface up to reasonable accessibility standards (ARIA roles, colour contrast, keyboard navigation)

Please audit the current repo, implement the fixes, then supply:
1. An updated codebase ready for production deployment
2. Before/after Lighthouse (or similar) reports demonstrating faster load times
3. A short changelog explaining what you tweaked for performance and UX
4. Add all payment methods via stripe

No boilerplate rebuilds—just pragmatic improvements that get this site shipping-ready. If you’ve tuned Supabase front-ends before and speak the usual toolkit (Vite, PostCSS, ESLint, etc.), let’s talk.
