/* --- House typeface: Figtree -----------------------------------------------
   Font policy 1b: Figtree for titles AND body across everything published
   online. Self-hosted, not Google Fonts: a third-party font request would
   sit badly with the same privacy stance that removed Turnstile from
   donaldjenkins.com. Single Regular cut, copied from that site's
   static/fonts/. These pages declare no font-weight and contain no heading,
   strong or em element, so nothing is ever synthesised.

   TO REVERT TO system-ui: delete this @font-face block, restore
     --sans: system-ui, "Segoe UI", Roboto, Ubuntu, Cantarell, "Noto Sans", sans-serif;
   and delete the fonts/ directory. Nothing else references Figtree.
