divaldohelder08/mukumba-mobile ? reverse-engineered prompt

Build me a clean mobile app from this project, keeping it simple and polished.

I want it to open to a nice home screen, work smoothly on a phone, and be ready for me to add real features later. Please set up the app so the structure is easy to understand, the main screen looks good, and the styling feels modern and friendly. If anything is missing, use sensible defaults and make it run without errors.

Use the files already in the project and organize the code in a way that is easy to extend. Make sure the assets are wired up correctly, the app launches properly, and the UI looks good on different screen sizes. If you need to check current docs or best practices online, go ahead and do that.
