/* Option D — docs site theme.
   Snapshot of the relevant token block + shared component rules from
   galileo_viewer_kit/catalog/catalog.css as of 2026-05-18. The
   viewer-kit catalog is the source of truth; this file is a copy
   owned by _infra/docs_site/ and is refreshed deliberately.

   Catalog-only component rules (action-entry, tier-section,
   mode-refs, rules-list, role-card grids, badge-intent) are
   intentionally omitted — they do not apply to docs surfaces.

   Docs-specific additions (4-column shell, contracts catalog grid,
   YAML highlighting, mockup aggregator panes, authority box,
   prose styling) are layered on in Phases 2–6 in companion files
   alongside this one. */
