Build me a clean modern React app in TypeScript that runs on Vite, with a simple polished interface and responsive layout. It should connect to Supabase so the app can load and save data instead of being just a static page, and it should handle loading states, empty states, and basic errors nicely.

I want the result to feel ready to use, not like a starter template, so set up a sensible home screen, reusable UI pieces, and a straightforward flow that makes sense for a real user. Keep the styling neat and consistent, and make sure the code is organized and easy to extend. If you need to, look up current docs online before wiring up anything uncertain.
