/* ============================================================
   CloudKey Infrasol — Design System
   Signature: the "keyline" — a literal key-cut (bitting) pattern
   used as a section divider. It's the one bold, repeated motif;
   everything else stays quiet so it can carry the brand.

   Color tokens are CSS variables, defined per-request in
   includes/header.php from the settings table (Admin > Colors),
   so this file must never hardcode a color — always var(--...).
