Build me a clean React app for a technical test that feels finished and polished, not just the default starter page.

I want a simple responsive front end with a nice layout, clear sections, and a few small interactive pieces so it shows good component structure and state handling. Make it easy to run locally with the usual React scripts, and keep the code organized and readable so it would be easy to review in an interview or test setting.

Use the existing project setup, add whatever components, styles, and sample data you need, and make sure it works well on mobile and desktop. If anything is unclear, make a sensible choice and keep it lightweight.
