Jetbrains Mono font is free and open source. You can bundle it

you'll probably want to include it in the repository using git-lfs

recommendation:
Copy fonts into assets/fonts/ and reference them in css.

but if you want to install it for the user, that'd be cool too. I used to always love finding new fonts on my computer that came from mystery programs.

mmm not sure how I feel about bundling it... Not everybody uses it !
