Apparently it's embedding actual TeX for this purpose: https://git.sr.ht/~sbinet/star-tex https://git.sr.ht/~sbinet/star-tex (TeX is written in a Pascal variant, and this kind of transpilation is by no means unusual.) It's common to have HTML widgets in GUI toolkits, and some may even support MathML, but this here is a bit different.
