astrit/css.gg ? reverse-engineered prompt

Build me a polished website and library for a huge collection of UI icons, glyphs, patterns, colors, and layout examples.

I want people to be able to browse the icons easily, search by name or style, open a single item, and copy the CSS or SVG version quickly. The experience should feel simple and modern, with clear categories for icons, glyphs, patterns, colors, and layouts, plus a way to switch between styles and see what each asset looks like in use.

It should work well as an open source project, with clean docs, a nice homepage, and obvious ways to use it in a design tool or in a normal web app. If you need to check current docs or best practices online, go ahead.
