shashikant-14/kanvet_web_app ? reverse-engineered prompt

Build me a clean React web app starter for Kanvet using the existing Vite setup.

I want a simple, modern interface that works well on desktop and mobile, with a nice landing page, a clear header, a main content area, and a footer. Keep the design polished and easy to use, and make the pages feel ready for a real product instead of a plain template.

Please structure the app in a sensible way with reusable components, basic navigation, and a few example sections so it feels complete. Use the current React setup in this repo, keep the code tidy, and make sure it runs smoothly with no errors.

If you need to check the latest React or Vite docs online for best practices, go ahead and do that.
