Have you considered the very low-tech solution of simple HTML anchors to link back and forth?

Definitely! That's what my goal implementation will be compiled to, anyway. I use Hugo, a Go static site generator, to build the markdown posts into the site. Adding footnotes is just a matter of figuring out how to use the right syntax in the markdown, output the right anchors in the HTML, then sprinkling a little CSS on top.

I'm 99% sure Hugo can do this, I've just learned to be wary of putting things in between myself and actually hitting the damn publish button.
