"Why does my site's text look nicer on Edge than it does on Firefox?" was not a question I expected to launch me into an hours-long rabbit hole culminating in the realization that I might need to use an entirely different font despite not liking any of my potential options, but here we are.
Anyway uhh I guess minor theming update coming in the future
what ended up being the reason?
I might do a blog post, but (I believe) a combination of an improper font import and difference in how bold text is rendered between browsers.
