Okay so I did a pretty bad job breaking this into discrete tasks here and explaining all the many many decisions made during this work, but some of it is in the CLC repo:
https://github.com/thinkshout/calc/issues/822
https://github.com/thinkshout/calc/issues/823

Also noting here that I did a lot of reformatting/4 space->2 space/nesting cleanup because I thought we were going to be supporting this site in the future - I didn't realize this was strictly a retheme for now.

Sorry for whoever ends up reviewing my work.

It might be worth making a branch from main that converts 4-space tabs to 2 and then merging there, so at least that noise isn't in the review.
