It's just this:

    p, .conversation-chat, blockquote, em, strong {
        font-size: 1rem;
        font-style: normal;
        font-family: Menlo, monospace;
    }

That's really the heart of it. I've wanted to try using a sans-serif font like Inter, but I'm stuck in a pit where people expect me to use a monospace font and any attempt to move away from that means I basically change a huge part of the site's visual identity. I'm still trying to figure out how to find some middle ground because I am told that the monospace font is hard for people with dyslexia to read.

I'll figure out something, I'm sure.
