I was talking to @tomglenn and we agree tha It's hard to know when Pathfinder's loaded a newly pushed to GitHub version of an interactive tutorial, and it's hard for users to report bugs against a specific version of a tutorial as there's no version displayed in Pathfinder.
Suggest that we use the GitHub commit hash for the unstyled.html file as the version identifier and have some sort of template markup in the unstyled.html file... this could then be populated by a GitHub action or something?
