/* ============================================================================
   VUBEX SiteOps - Shared Component Library
   ----------------------------------------------------------------------------
   Single source of truth for reusable UI primitives (cards, buttons, status
   pills, empty states, toasts). All classes are prefixed `vx-` so they never
   collide with, override, or alter existing page-specific styles.

   Built on the design tokens declared in styles.css :root
   (--primary, --surface, --text-primary, --success, --error, --warning, ...).
   Pages should <link> this file and use these classes for new/consistent UI.
