also fixed flicker that i introduced in the last commit
this font is not used anywhere outside of the download button, so it makes no sense to load the entire font
it feels unnatural in safari and other browsers with colored headers
most browsers have their own frame nowadays (for some reason) so in those it looks even weirder than in regular ones (such as helium). just a waste of space.
- prevents conflicts with existing box-shadow(s) on basically all components
- removes the need for data-focus-ring-hidden or any other weird workarounds
