Follow-up work to #8791 now that the page is live!

uhhhh the tests are failing because linking with cc failed because there's no space left..... does a cache somewhere need cleared?

We're 100% going to forget this, aren't we?

I wonder if we should have a scheduled GitHub action that monitors this and tells us if it's close. (I can write that after this gets merged.)

hmm, that's a good point. I guess alternatively the file is small enough that we could also generate it on startup and serve it from the axum server 🤔

well the point is that a person should look at it every once in a while.........

(At least) #9030 also failed for the same reason. Weird.

I've opened #9050 and will see what I can figure out. (Decidedly not a CI or GitHub Actions expert over here.)
