win-mice/Mices-s-test ? reverse-engineered prompt

Build me a simple starter app for this repo, something I can run right away and see working. Keep it clean, minimal, and easy to understand, since there is basically no existing info here to follow. If the project needs any setup decisions, make sensible choices and keep everything as small and practical as possible.

I want a basic polished screen, a little bit of interaction so it does something useful, and a structure that would be easy to build on later. Please also make sure the README explains how to run it and what it does. If you need to check current docs or best practices for anything, go ahead and look them up online and use the latest stable approach.
