AlexInABox/zeitvertreib-website — reverse-engineered prompt

Build me a clean website and repo for the Zeitvertreib plugin collection. I want a simple public site where people can see what Zeitvertreib is, browse the different plugins, read basic documentation, and check the changelog. Each plugin should have its own page with a short description area, setup notes, and a place for future examples or screenshots.

Please set it up as a monorepo with a frontend, a small backend, shared types, and the existing C sharp plugin projects kept together neatly. The site should feel modern but lightweight, easy to maintain, and not overdesigned. It should work well on mobile and desktop.

Use TypeScript where it makes sense for the web parts, keep formatting consistent, and make it easy for me to add more plugins later without rewriting everything. If you need current docs for the tools, look them up online.
