This article lists all the typefaces I make use of on the wiki or the site as a whole.
Additionally, I make use of M PLUS Rounded 1c alongside Vollkorn, FiraCode, and the others in images and whatnot. I will usually explicitly state what typeface I’m using under the source for the image or whatever it is.
I attempted to switch to using M Plus 1p for the main text, but found that it’s not very well suited for that purpose. I consider this a shame, as I really liked the look of it.
