nostr-protocol/nostr ? reverse-engineered prompt

Build me a simple, polished website for Nostr that explains what it is in plain English and helps new people understand why it matters.

I want the page to feel approachable, not technical, with a strong headline, a short explanation of how notes go to relays and how people follow public keys instead of usernames, and a clear section that walks through the basic flow with the included diagram. Add a few sections for why it works, what relays are, and where to learn more, with links to the protocol spec and getting started resources.

Make it look modern and trustworthy, with responsive layout, clean typography, and a layout that works well on mobile and desktop. If it helps, include a simple call to action that points people toward trying Nostr for themselves. Keep the content accurate to the README and don’t invent features. If you need current docs or examples, look them up online and use the simplest version that makes sense.
