GreyXor/Windows-11 ? reverse-engineered prompt

Build me a simple web app that lets people browse this historical source code archive in a clean, easy way.

I want the homepage to explain that this repo contains old MS DOS and Windows 11 source material, then let users open each version folder and read the files without having to dig through the repo manually. Make it feel like a neat archive or museum exhibit, with a searchable file list, code preview, and a clear way to switch between versions like v1.25, v2.0, v4.0, and v4.0 ozzie.

Keep it lightweight and polished, with good default styling and a layout that works on desktop and mobile. If you need to look up current docs online for the best way to do the file browsing or syntax highlighting, go ahead. I mainly want something that makes this old code easy to explore and understand, while keeping the historical feel intact.
