Welcome to the forum @cms81 !
Typst does have an official logo: “typst” in bold Buenard font with color #239dad, with some kerning adjustments for the SVG version which you can get here.
The rules governing usage of this logo are given here. My understanding is that you can use the logo to make your own T-shirts and mugs but you would need permission to sell them.
To clarify:
-
The logo is for use in places where a logo makes sense (and on a T-shirt or mug anything makes sense
) -
For references to the project in regular text you just write Typst without a special font. Quoting the GitHub readme:
When writing about Typst, capitalize its name as a proper noun, with a capital “T”.
and core developer Laurenz on discord:
The logotype is lowercase, but the name in text is capitalized. You also shouldn’t use any special font for the logo (like TeX does). It is supposed to fit in the with the surrounding text.
