radix-ui/website ? reverse-engineered prompt

Build me a polished documentation website for Radix UI that feels clean, modern, and easy to browse.

I want it to showcase the design system clearly, with a strong homepage, documentation pages, component pages, and useful navigation so people can quickly find components, colors, icons, templates, and guidance. Make it look like a real product site, not a generic docs page, and keep accessibility in mind throughout since this is for an accessible UI library.

Please make it work well on desktop and mobile, with responsive layouts, good typography, search friendly content structure, and reusable page sections so the site is easy to maintain. If you need current best practices or library docs, look them up online while you build.

It should be ready to run locally and feel like a production quality Next.js site for an open source project, with the documentation content presented in a clear, friendly way that matches a high quality design system brand.
