   references-viewer.css — schema-aware document viewer styles
   Used by Central / Academic / Teachers Hub references modal viewer.
   Source of truth: monorepo-root /shared-design/. Each hub copies this
   into its dist/ at build time (with a local-copy override for
   standalone deploys).
   Depends on the host page providing CSS variables: --accent,
   --accent-dk, --accent-2, --ink, --ink-2, --ink-3, --border, --paper,
   --white, --shadow-sm. All hubs already define these.
