This is already looking better.

(Also, for the record, this is just a me thing and not official policy or anything, but I’d find it easier if you didn’t force-push because then I’d have an easier time telling what’s changed in recent commits; everything is going to get squashed into a single commit on merge anyway, so individual commits to the pr don’t have to be perfect or anything.)
