Just 2 nits. Let me know if you'd prefer me to add commits to your fork for changes like this - I'm still getting used to github etiquette.

Disclosure: both of these were flagged by copilot, but I looked into them and they seem useful to address.

What do you need me to do? I also know very little about GitHub's rules.

Thanks for the improvement! Only one small styleguid nit, otherwise LGTM.

I also marked Alan again for re-reviewing.
