Build me a simple TypeScript web app with a small frontend and a server side API, set up so it can run locally and also deploy cleanly on Vercel.

I want a clean starter project that actually works end to end, with a basic page in the browser, a backend route or two, and a nice placeholder experience for testing. Keep the design simple and modern, and make sure the app can be opened right away without extra setup headaches.

If anything is unclear, use sensible defaults and look up current docs online if you need to. I mostly want a solid working foundation that I can build on later, with the frontend and backend wired together properly.
