I'm curious why you avoided using mdx-prism in favor of re-implementing much of it yourself. If only because I just used it in my own project and spent time patching a minor Firefox-specific bug, and now I have FOMO because I like your implementation here :) Were your features impossible without huge changes? I do like that you use the `line=1-3` syntax for highlighting instead of mdx-prism's `lang{1-3}`. Do you have any appetite for upstreaming that change?
