   EventuallyWrong.com — custom styles layered over quark2.
   Direction: minimal & modern, with one characterful "case file" accent
   (the Rule 51 card). This file loads AFTER quark2's theme.css, so these
   rules win on conflicts. quark2 already provides Cal Sans (headings),
   Inter (body), light/dark, and the --q2-* accent variables.
