Enable us to use tailwind's [`font-family`](https://tailwindcss.com/docs/font-family) classes as well as remove `gt-mono` in favor of `tw-font-mono`. I also merged the "compensation" to one selector, previously this was two different values 0.9em and 0.95em. I did not declare a `serif` font because I don't think there will ever be a use case for those. Command ran: ```sh perl -p -i -e 's#gt-mono#tw-font-mono#g' web_src/js/**/* templates/**/*
