/* ------------------------------------------------------------------
   Palette and structure follow how the University of Copenhagen uses
   its own identity on ku.dk: a KU-red band above the masthead, black
   serif display headings, sans-serif body text, red reserved for
   labels, figures and rules, a light grey panel for exhibits, and a
   solid KU-red footer block.

   KU-rød #901A1E and KU-grå #666666 are the two values KU publishes
   (designguide.ku.dk). The warm neutrals are derived around the red.

   Single theme, deliberately: lightening KU-rød for a dark ground
   turns it into a coral that belongs to no one.
