Build me a simple React Native starter app that runs on both iPhone and Android and looks polished right away.

I want the app to open to a clean home screen with a friendly welcome message, a short description, and a couple of tappable buttons or cards so it feels like a real app instead of an empty template. Keep the design modern and lightweight, with good spacing, readable text, and a nice color palette. Make sure it works well on different screen sizes and still feels good in dark mode if that is easy to add.

Please wire it up so the app launches cleanly, the main screen lives in the existing app entry point, and the code is organized in a simple way that is easy to edit later. If you need to check current React Native docs online, go ahead. Also make sure the project still builds and runs without any extra manual cleanup.
