   House standard: named tokens, no Inter, no emoji-as-UI, 8px scale, one radius

   FONTS ARE SELF-HOSTED, and that is a POPIA decision as much as a speed one:
   pulling a webfont from a CDN on the VISITOR page would send a stranger's IP
   address to a third party before they have agreed to anything. Everything the
