Can we get browsers support for markdown now, please?
This is a really nice new Cloudflare feature: on-the-fly markdown conversion. Tools like Claude Code send an "Accept: text/markdown" header when making web requests. If you enable this it, it will send these agents a markdown version of your page instead of the full HTML. Really good for docs.
Introducing Markdown for Agents
Cloudflare's network supports real-time content conversion to markdown at the source.

I've been using a version of blog.zsa.io/layout-buffe... for some time now but somehow, this ZSA config is worse than what you can do with QMK code...
Anyone is using this successfully?
