/* ===========================================================================
   HIVE legacy-domain transition landing — v2 design system
   ---------------------------------------------------------------------------
   Shared tokens + components for the three v2 concepts. Concept-specific
   layout lives in each page's own <style> block, namespaced by a body class:

     .c-showcase   Concept A — dark product showcase
     .c-corporate  Concept B — light corporate
     .c-notice     Concept C — compact notice

   Constraints this file must keep honouring (see the cutover runbook §4.1):
     - no external fonts, scripts, analytics or network requests of any kind
     - WCAG AA contrast, visible keyboard focus, reduced-motion respected
     - readable from 360px through 2560px
   ======================================================================== */
