/* ============================================================================
   CLARITIQ ADMIN — DESIGN SYSTEM
   ----------------------------------------------------------------------------
   Single source of truth for the admin portal's visual language.

   Every page under admin.claritiq.io includes this file. It owns:
     - design tokens (colors, type scale, spacing, radius)
     - body reset + base typography
     - the dark canvas (background grid + brand-color glow)
     - the page wrapper (.admin-main) and page-head primitives
     - shared components used in two or more pages: stats display,
       filter pills, stat pills, filter sidebar, view switcher

   Page-specific CSS lives inline in the page (e.g. the cards grid on
   the backlog page, the D3 tree styling on the tree page). Anything
   used by 2+ pages should land here instead of being copied.

   See _portal/README.md for the page contract (skeleton + rules).
