What if there was an internet browser based on rendering Markdown? Sans HTML, CSS, JS and whatnot? Without all the bloat that makes publishing complicated? With meta-data driven by Frontmatter? With great typography standards?

Focused on written content? And that's about it?

That's unfortunately right - most browsers removed support for the Gopher protocol in the last ten years or so :(

However, there seem to be extensions that re-enable it (usually by routing requests through some Gopher-to-HTTP proxy because of technical limitations of the extension APIs). No idea if they're any good. And even if they work - keep in mind that Gopher is basically a ghost town by now :)
