Build me a clean modern React app using this existing Vite setup.

I want a polished starter site with a simple home screen, a few reusable components, and basic navigation so it feels like a real product instead of the default template. Make it responsive, easy to read, and pleasant on mobile and desktop. If there’s any setup work needed, wire it up in the app so I can run it right away.

Please keep the code organized and use sensible React patterns. Add a nice placeholder experience for the main content areas, and make sure the project builds cleanly with the current linting and Vite setup. If you need current best practices, look them up online first.
