I poked around on those links and I have yet failed to find any use of this Lisp in that font project. Looks like he just built everything with Javascript

  The glyphs themselves are written in PatEl: see https://github.com/be5invis/Iosevka/blob/main/packages/font-glyphs/src/letter/latin/lower-a.ptl https://github.com/be5invis/Iosevka/blob/main/packages/font-... for instance. If you look through the commit history, you can see Be5invis gradually elaborating the font itself by editing these files. Javascript is used as the build language, but not to define the characters.
