This screenshot has localhost as the domain for the preview and study links, which maybe isn't ideal but not a big deal either.

Many users won't be familiar with GH, so it might be useful to show more of this page, e.g. full width and just from top down to the commit info. Then again, maybe it doesn't matter because I'm not sure how useful this section is anyway. I think it's much easier for users to just click the "Check for updates" button on the site, read commit descriptions and grab the commit SHAs there.

Do know if these links names/references are case-sensitive? In "study list page", the "s" is lower case here and upper case where it's referenced in the text above. I had a quick look in the sphinx rst docs here: https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#hyperlinks but couldn't find a quick answer.
