   One stylesheet, three module skins. Every colour lives in the token block
   below; no rule further down may contain a hex literal. Module identity is
   carried by three custom properties (--accent, --accent-deep, --accent-tint),
   so a new module is a four-line addition to the THEMES section and nothing
   else.

   Palette and geometry were measured out of the approved PDF flyers rather
   than eyeballed. See website/README.md.
