Super helpful, thanks for being willing to post your configs!

Hey, take a look at this user's post, they set up their instance with docker and posted their compose and config files. I was able to get up and running using that.

You probably noticed when you were messing around with Jerboa, but you can decrease font size in the Look and Feel settings. I found the app unusable until I did that.

I'm not sure what the problem is specifically in your case, but I did have a hell of a time setting up my instance using docker. I was eventually successful using this user's docker compose and config files from this comment. I had to start over completely from scratch by pruning all of my unused images and networks (sudo docker system prune -a) in between installs, as well as starting fresh with a new docker/lemmy/ folder before everything worked. Hope this helps!
