I added a few modifications to the OSS Ghost theme that powers this site. You can get it here: https://gitlab.com/matdevdug/minimal-ghost-theme

• Added better image caption support.
• Added the cool Mastodon feature outlined here to attribute posts from your site back to your Mastodon username by following the instructions here.

I tried to make it pretty easy to customize, but if you need something changed feel free to open an issue on the repo. Thanks for all the feedback!
