• [nitpick] Inconsistent indentation detected (a tab is used on this line). Convert all leading tabs to spaces to match the surrounding entries.

This looks good to me, @hornc. I'm going to commit the change suggested here, then merge this in.

@jimchamp uh, the AI suggested change was crap though. It wasn't in alphabetical order. I wasted time checking it, c an we revert it?

Looks like f-string literals cannot be used in our templates, and book pages are not rendering after these updates. Will open a PR reverting those changes shortly.
