microsoft/react-native-windows ? reverse-engineered prompt

Build me a simple React Native for Windows app that I can open and run on Windows, with a clean home screen, a welcome message, a few basic interactive controls like buttons and text input, and a second screen or panel that shows a bit of app state.

I want it to feel like a polished Windows desktop app, not just a web page, and it should work well on regular PCs and tablets. Please make the UI modern and friendly, and use the normal React Native for Windows setup so it’s easy to run and extend later.

If you need to, look up the current React Native for Windows docs online so you use the right setup and any latest recommendations. Also make sure the code is organized clearly enough that I can add more screens and native Windows features later.
