+//   A. the TYPE REGISTRY: 'country' is registered, an unknown type is null, a plugin can register its own.
+//   B. SCOPES: DX Life's /regions slugs (africa … oceania, other) each resolve; every spelling of a region (its
+//      slug, its API value, its English name) resolves to the same countries; the scopes cover all countries once.
+//   C. a WITHHELD whole-country poster stays withheld through the type (the card's sentence; its rows rejected,
+//      no records fetched).
+//   D. the ELEMENT's attributes map to its config (collapsible on by default, collapsible="false", collapsed).
+//   E. THE LIFT: every name PosterSection.vue's template uses is injected from the wall (a section never reads
+//      something its wall does not provide).
+// --self-test: a registry without 'country', a region key without "&" → "and", and a section template that uses a
+// name it does not inject must each FAIL. Loaded through Vite (the @map alias), like check:poster-wall-host-seams.
