Easter egg: The favicon is an upside down Codeberg logo.
Am I understanding correctly that this is Codeberg pages, but for git repos that are not necessarily (but especially designed for those which are) hosted on Codeberg?
It uses completely different software (that I wrote together with a small team of volunteers: https://codeberg.org/git-pages/git-pages) which scales very well horizontally and works more like GitHub Pages than Codeberg Pages technically, but in concept you are basically correct.
I started using Codeberg 2 months ago and I'm shocked how great and simple is it!
Highly recommended, especially if you actually hate keys instead of passwords ;)
You can add X-Clacks-Overhead as a custom header. Nice.
Does it work with Tangled?
Yup, you can use something like:
$ curl http://yourdomain.org -X PUT --data https://tangled.org/@yourname.tangled.sh/site
from a CI pipeline, or just upload an archive from the same (if you use "Method B" for authorization).
