Lemmy does come with a standard web interface that you could apply custom css to. If that custom css then federates, other instances could show it on their end.
Might clutter the Lemmy API with stuff that less than half of users actually wants to use though. Maybe it’s better to make a separate system of fediverse user styles with a browser plugin. Then someone on Mastodon could also see it without having to extend the entire ActivityPub standard.
This seems significantly harder to achieve here. I believe Lemmy doesn’t have a unified frontend across instances, or does it?
