Fully armed and operational
Was able to get indie auth, webmentions, Mastodon verification and umami up and running. Hit a small snag with my not understanding how the header/footer injection worked in Pure Blog but was able to find help on the Github repo.
This blog is about as setup as it can be. I struggled with all of the above integrating into my Hugo implementation but was eventually able to get them all (mostly) working. This was infinitely easier with Pure Blog.
A small note on the Umami analytics; I've never had anyone other than myself visit the site. It's really just there to say that it's there and get the experience of setting up and admin'ing all the different parts you can admin and set up in a personal website.
