/* w3trine registry — a credential office, grounded in passport materiality.
   Design contract (acceptance criteria, not styling):
   - Only .proven carries authority (stamp green + seal + check).
   - .claimed is attribution, never endorsement (neutral ink, "asserts", no gold badge).
   - Void (revoked/expired) dominates: desaturated body under a rubber-stamp overlay.
   - not-yet-evaluated is a confident, deliberate empty state — never a zero or stars.
   Deliberate single visual world: a light physical document. */
