Igguimaraes/projet-control ? reverse-engineered prompt

Build me a clean React app for a simple control panel frontend.

I want a modern, responsive interface that feels polished on desktop and mobile, with a clear layout, navigation, and a main area where I can manage or monitor things easily. Keep the design simple and professional, and use the existing styling setup in the project. Make sure the app runs smoothly in Vite, and organize the code so it’s easy to extend later with more pages or features.

If anything is unclear, make sensible choices and keep the implementation practical. Also check current docs online if you need to confirm any best practices.
