All this works and looks good.

Question: Are there not other changes we needed to make for Svelte v5? I guess they aren't required based on the style guide, but perhaps we need an issue to remember to go back and update everything?

While their migration script didn't work, they also said most projects can upgrade and just fix errors and warnings. I looked over some of the migration notes for Svelte5, and this repo wasn't really using anything that was affected by the breaking changes (e.g. svelte:component is now svelte:element). I fixed all of the warnings and errors.
