RefineDevelopment/Documentation ? reverse-engineered prompt

I want to build and polish the Refine documentation site from the existing MDX content.

Please make sure the docs site runs cleanly, looks consistent across pages, and follows the same layout and structure as the current documentation. Focus on the home page, sidebar navigation, and the docs pages in the existing content, so everything feels organized and easy to browse.

If anything is missing or broken, fix it so the site starts normally and the documentation reads well in the browser. Keep the styling simple and professional, and match the current Refine docs feel instead of changing the whole design. If you need to check the latest Docusaurus docs or other references, go ahead and look them up.

When you’re done, make sure the project is ready for a pull request with only the needed changes.
