Build me a simple modern web app in TypeScript that feels polished and ready to use. I want a clean homepage, a basic app shell, and a few practical screens for viewing and managing data, with everything wired up so it actually works end to end.

Use the existing project setup, keep the UI responsive and straightforward, and make sure the database layer is connected so the app can save and load records properly. If anything needs current setup details from the latest docs, look them up online and use best practices.

Please also include sensible error handling, loading states, and a basic test setup so I can verify the main flow. Keep the code organized and easy to extend later, and make sure the app runs cleanly from the start.
