/* ============================================================================
   QIIUB Internal Wiki — Shared Stylesheet
   ----------------------------------------------------------------------------
   Single source of truth for visual identity across every page on
   wiki.qiiub-internal.com. Each diagram still owns its own layout (sidebar,
   tabs, graph viz, etc.) but inherits typography, colors, callouts, tables,
   and form primitives from here.

   Aligned with:
   - packages/qiiub-ui/DESIGN-SYSTEM.md
   - docs/mockups/portal/_shared.css (same brand purple, same token names)
