   FLIBBR — verify.css
   Drives /verify/ (page-verify.php).

   Lifted verbatim from locked canonical
   `flibbr-design-mockup-final-verify.html` (v1, locked 4 May 2026).

   SCOPE
   This file covers verify-specific selectors only:
     - .verify-search, .verify-search-*
     - .verify-filters, .verify-filter-label, .verify-pill
     - .verify-main, .verify-cohort, .verify-cohort-*
     - .verify-section, .verify-section-*
     - .verify-cred-grid, .verify-cred-card, .verify-cred-*
     - .verify-no-results, .verify-no-results-*
     - .verify-lightbox, .verify-lightbox-*

   Site header + footer chassis remain in header-footer.css.
   Container, body, focus rings remain in base.css.
   Tokens are global in tokens.css.

   ONE LOCAL TOKEN
   --terracotta (#b4431b) is verify-archive only — sampled from the
   certificate colour band, used exclusively on credential IDs as a
   visual rhyme with the artifact being verified. Defined here, not
   in tokens.css, because it is genuinely scoped to this surface
   (canon comment lines 145–149).
