BrianRuizy/b-r.io ? reverse-engineered prompt

Build me a clean personal website for Brian Ruiz that feels minimal and polished, with a homepage, writing or blog section, projects, and a uses page. It should look good on mobile and desktop, with smooth subtle motion and a modern portfolio vibe.

I want the writing section to use MDX for posts, and the site should support things like a canonical URL, sitemap, and RSS feed. There should also be a simple newsletter signup connected to ConvertKit, and a small map based blog demo that uses Mapbox if the token is set.

Use a simple elegant design with Tailwind, keep the content easy to edit, and make sure the app is set up to run locally with environment variables from a .env.local file. If you need to check current docs for Next.js or any of the libraries, go ahead and look them up online.
