LibreChat-AI/librechat.ai ? reverse-engineered prompt

Build me a polished documentation site for LibreChat, with a home page, docs, blog, and changelog, all in a clean modern style. It should feel fast, readable, and easy to browse on desktop and mobile, with light and dark mode, strong search, and good navigation for a large docs site.

The content should be written in MDX, and the site should support multiple languages, with English as the main source and translated pages where available. I also want an in page AI helper that can answer questions from the docs, plus a search experience that feels instant. Make it feel like a real product site, not just plain documentation.

Use the current docs and any online references you need if something is unclear. Please make sure the result is production ready, organized, and easy to extend later.
