/* ==========================================================================
   CAYVOT SYSTEMS — design tokens
   Concept: the site reads like a capability statement / spec plate, not a
   startup landing page. Graphite + paper, one signal-orange accent used only
   for status and calls to action, mono type for codes (UEI/CAGE/NAICS).
