Build me a small polished web app in TypeScript that feels like a real product, not just a demo. I want a clean single page experience with reusable UI pieces, sensible shared state, and a simple service layer so the app is easy to grow. Add a lightweight server for anything that should happen outside the browser, and wire in environment based config with an example env file.

Please keep the code organized and readable, with clear types, basic error handling, and a smooth developer setup so I can run it locally without fighting the project. The main screen should feel modern and responsive, and the app should have enough structure for future features, like dedicated components, hooks, contexts, and utility code.

If something is missing, make practical choices and keep the scope reasonable. You can look up current docs online if you need to. I mainly want a solid full stack starter that looks finished and is easy to extend.
