   primae-vandv.css — V&V attestation playground.
   Three problem chips drive an instrument panel: a battery of
   check rows lights up with pass ticks (zone A) while standards
   clauses cite in, a confidence bar fills, and an attestation
   card stamps with a dashed accent seal (zone B).
   Scoped under .pm-vv-* · warm-light tokens with fallbacks.
