ra559/linux_cheat_sheets ? reverse-engineered prompt

Build me a clean static website for a set of Linux cheat sheets for a class.

It should take 18 Markdown cheat sheets and turn them into individual HTML pages with a shared layout, a homepage that lists every sheet, and a section that highlights the four newest ones. I want a sidebar or navigation that makes it easy to jump between sheets, and each page should have a simple table of contents generated from the headings.

Keep it as a static site, no app server, no database, and no Node setup. Make it work with Jekyll so I can build it locally and serve the generated files from a plain web server. Please wire up the homepage, templates, styles, and any small bit of JavaScript needed to read the generated cheatsheet list. If you need to check current Jekyll docs or syntax details, look them up online.

Also make sure it is easy to deploy on a Debian server or in Docker, with the built files landing in a _site folder.
