/* =============================================================================
   Pep Research -- Documentation (coas.html), CEO direction 2026-09-30:
   a compact header, then the certificates as dark glass cards. The page hero,
   the breadcrumbs, buttons and the card light come from css/v3.css; colors
   from css/v3-palette.css. Every value on a card is transcribed from the
   certificate file it opens (images/coas/). The viewer (#docViewer) is a
   native <dialog> driven by js/v3-docs.js; without it, "View Certificate" is
   a plain link to the file.
