The thing that's problematic is rendering Mermaid SVGs outside of a browser environment - i.e. what static site generators need in order to generate JS-free HTML docs from Markdown content.

If you're looking at a rendered Mermaid diagram on your screen, you probably already have the SVG in your browser's dom. You can just right click -> view source -> find element -> view as html -> save that to a file. I expect this is how the SVG export on the Mermaid live editor[0] works.

(the Mermaid live editor is great, it's where I tend to go if I want an SVG export)
