/* =========================================================
   CERTIFICATE — navy/gold design, two selectable variants
   (classic / award). Copied exactly from the reference Quiz
   Platform app's certificate design, per spec — this is the
   one part of the visual system deliberately NOT reskinned to
   the site's own brand palette. Sized to an A4-landscape ratio
   so printing looks right, but scales fluidly on screen.
