Yes, it’s mentioned in the docs. It’s unlikely that regular Micro.blog customers stumble upon it, though, as static file hosting is a feature targeted at theme builders and plug-in developers.
You can add them as static files under the “static” folder in the plug-in.

includeswith the path “/hello.css”.
