creativetimofficial/ui ? reverse-engineered prompt

Build me a modern Creative Tim UI site and registry driven component library for Next.js.

I want a clean docs and showcase experience where people can browse pre built React components and blocks, see what each one looks like, and copy or install them into their own project with a simple command. It should support adding one component at a time or installing everything at once, and it should feel like a polished shadcn style workflow.

Please make the pages look production ready, with nice previews, clear component details, block categories like app UI, marketing, ecommerce, and web3, plus a straightforward way to use the CLI commands. If you need to check current docs or patterns online, go ahead.

Also include the pieces needed for the registry and a small mock API so the install flow works smoothly, and make sure the app is set up to be easy to extend with more components later.
