Pratim-Nag/Hackathon ? reverse-engineered prompt

I want you to turn this empty hackathon repo into a simple working starter app from scratch.

Make it something clean and presentable for a demo, with a home screen, a short welcome message, and a few obvious sections a judge can understand at a glance, like what the app does, a button or two to interact with it, and a basic results or status area. Keep it polished, easy to run, and make sure the project builds without errors.

Use the existing Gradle setup and fill in whatever source files are needed. If you need to check current docs or best practices online, feel free to do that. I mainly want a solid, finished looking app that someone can open and immediately understand, even if the content is simple.
