MRVIVEK-CODER/XD ? reverse-engineered prompt

Build me a simple Termux command line tool like this repo, with a retro terminal look, a startup banner, and a main menu that feels like the screenshots. I want it to run from the phone terminal, install cleanly with the usual Termux setup, and be easy for someone to launch after cloning the repo.

Please make it feel polished, with colorful text, a clear warning screen, and a few menu options that can be filled in with educational demo actions or placeholders if the real features are not obvious from the repo. Keep the app lightweight and focused on the terminal experience, not a full GUI.

Also include a short README that explains how to install and run it in Termux, and make sure the project structure is simple so I can tweak the menu or text later. If you need current Termux or Python package details, look them up online first.
