/* ============================================================================
   CyberKnights Robotics: store styles. Loaded per view on top of site.css via
   $data['styles'], for /shop, /shop/<handle>, /cart and /checkout/success.

   Deliberately token-driven rather than self-coloured: everything here reads
   --card / --line / --ink / --accent-text from site.css, so the store inherits
   the violet theme (and would follow a .theme-light section) instead of
   carrying a second palette that has to be kept in sync with the first.
