Spirizeon/superminimalism ? reverse-engineered prompt

Build me a super minimal landing page for a personal site that feels fast, clean, and a little bit opinionated about why simple web design wins. I want it to be a tiny pure HTML and CSS site, with no JavaScript unless it’s absolutely necessary, and it should be ready to deploy on Cloudflare Pages or another edge host.

Make the page look polished but stripped down, with strong typography, clear sections, and a simple message about performance, SEO, AI search friendliness, and security. Please include the important meta tags, social sharing data, schema, robots, sitemap, and llms.txt style support so it’s easy for search engines and AI tools to understand. Keep the whole thing lightweight and fast, with accessibility in mind and a mobile friendly layout.

If you need current best practices for metadata or structured data, look them up online. I’d also like a few example secondary pages that match the same style, and everything should feel like one cohesive tiny website rather than a big app.
