graphql/graphql-spec ? reverse-engineered prompt

Build me a clean documentation site for the GraphQL specification.

It should take the markdown files in the spec folder and turn them into a readable spec website with a homepage, a draft version, and stable release pages for tagged versions. The site should make it easy to browse the spec, jump between sections, and copy direct links to specific parts. Please keep the design simple and polished, with a strong focus on readability on desktop and mobile.

I also want the main README content reflected somewhere on the site so people can quickly understand what GraphQL is and where to find the latest draft and released versions. If you need current docs or build details, look them up online and match the existing project style as closely as possible.

Make sure the result feels like an official spec site, not a marketing page, and keep everything centered on the actual specification content.
