fizzle

Maybe everyone already knows this but you can generally see better in your peripheral vision in low light.

Almost all of your color vision / cones are concentrated in a tiny central area of your retina.

The grey scale / rods are dispersed around that.

In some ways I think night vision is a kind of skill that some people might be better at than others, even if the mechanics of their eyes aren’t special.

Yeah me too. I think this is called “coil hum”. I notice it with things like usb-c thunderbolt ports. Often you can swap a cable or something and it’s resolved.

I’ve been trying to get zulip working.

Sounds like it addresses your requirements.

Seems to be a real bitch to self host - I’ve been doing this a while but the compose yaml is pretty arcane with hundreds of environment variables.

I didn’t “give up” exactly but it’s been on the back burner for a month or so now.

I’m honestly kinda surprised that Google is apparently not in fact doing this already and (according to the comments here) continues to not do so.
