   My Desktop CertVault — certificate.css
   Certificate visual + print/PDF/PNG styles.

   Design goals:
   1. Use the four Google colors (#4285F4, #DB4437, #F4B400, #0F9D58)
      as a coherent palette so the certificate matches the site header
      and the brand mark.
   2. Keep the certificate on a single A4-landscape page when exported
      to PDF (locked via aspect-ratio: 1123/794).
   3. Support TWO signature blocks side-by-side, each loaded from a
      per-row file name in /branding/signatures/ (or ONE signature —
      the footer rebalances automatically).
   4. Support all 17 certificate types: the shared frame (header /
      issued-by / footer) plus a per-type middle section (.cert-body)
      that may include a From-To period box, a score box, and optional
      detail chips.
   5. Overflow safety: every text element is clamped (max-height +
      overflow:hidden) so long data can NEVER overlap neighbouring
      elements or the signature footer on the fixed 1123 × 794 canvas.
