   One rule governs colour: BLUE MEANS THE FAULT. #1B4FC8 is reserved for the
   curveball, for the moment a requirement changes, and for the primary action.
   It is never used as generic decoration — if something is blue on this site,
   it is because a change happened there.

   Navy is structural, not decorative: full-bleed navy bands mark the sections
   that describe the supervised room. Paper marks the sections that describe
   what the outside world reads.
