    Just curious, why does no-littering need the explicit require?

    It might not. Assume at least half of this was made when I was drunk.

    Not a fan of code ligatures but I know a lot of people like them.

    I did this when Emacs first rolled out the Harfbuzz engine. I could take it or leave it personally, and it only works if the correct fonts are installed.
