I FIXED MY .Pages
Too tired to make it make sense. My site broke under Hugo .58. No front page listing. I fixed it. Yay!
Instead of (for notes):
{{- range first 1 (where .Pages "Section" "note") -}}
I used
{{- range first 1 (where .Site.RegularPages "Section" "note") -}}
I also fixed the RSS feed, and updated the feeds post with those (very similar) details.
