/* ==========================================================================
   GapSure design system
   --------------------------------------------------------------------------
   The visual language is survey instrumentation: measured spans, tick marks
   and dimension rules. The brand is about the distance between where a
   business is and where it could be, so structure is drawn, not decorated.

   Monospace is reserved for values that were actually measured — scores,
   header names, counts, URLs. It is never used for labels.
