slatedocs/slate ? reverse-engineered prompt

Build me a beautiful static documentation site for an API, with a clean reading experience, a left side navigation, and nicely styled content that feels polished and easy to scan. I want it to look good out of the box for developer docs, with support for long form guides, endpoint reference pages, and code examples that are easy to read. Keep it simple enough that someone can use it to publish docs for a product without needing to design anything themselves.

If you need to, look up current docs online for any tooling details, but mostly focus on making the site feel fast, modern, and ready to deploy as static documentation. I care more about a great looking result and sensible defaults than a bunch of extra features.
