K25SW01/OpenHack ? reverse-engineered prompt

Build me a clean, simple starter app in this repo, since it looks basically empty right now.

I want something polished that opens with a friendly home screen, explains what the project is for, and gives me a clear place to add more features later. Keep it easy to run, easy to understand, and organized so I can extend it without fighting the setup. If you need to make any choices about the best current approach, go ahead and use the modern default that fits this kind of project, and look up current docs online if needed.

Please also leave me with a short README that explains what it does and how to run it, plus a sensible project structure so this doesn’t stay as just a test file.
