YOU CAN CHANGE FONTS??? or am i stupid.

Sort of. You can change them using custom CSS, for example I have:

body, button, input {
  font-family: monospace, "Noto Mono";
}

but if someone viewing your profile doesn't have the font installed it won't work. Hence why I used monospace, so that it uses the default console font of your PC.

Yeah, it's a bit finnicky. I wouldn't recommend messing with custom CSS unless you're well versed in Inspect Element.
