I ran make serve-dev in the /site folder to host it locally, then in Safari exported the page as a PDF. I imagine most browsers can do the same. I think some make you go to a Print dialog first and then "print" to PDF.

i had a weird formatting issue when using chrome, maybe safari is the answer 😄 thanks!
