pure-css/pure ? reverse-engineered prompt

Build me a small, responsive CSS library for websites and web apps that feels clean and minimal, not flashy.

I want it to include a simple grid system, button styles, menus with dropdown support, form layouts, and a few common table styles. It should be lightweight, easy to customize, and work well in modern browsers. Please also make sure there’s a solid base style so things look consistent across browsers, and include both responsive and non responsive versions where that makes sense.

Along with the styles, set up a basic project structure so the CSS can be built from source, and make it easy to generate minified production files too. If there’s a docs or demo site in the repo, keep that working and make the examples look polished.

If you need to check current build or browser compatibility details, look them up online.
