/**
 * Framed certificate ("Photo View") for the Certificates page viewer.
 *
 * Loaded only on the Certificates Page template. Every selector is prefixed with
 * `ks-certframe` (or scoped under `.certificate-viewer.is-photo-view`) so the
 * plain full-size viewer keeps its existing appearance untouched.
 *
 * Two frame variants are supported:
 *   .ks-certframe--image  A frame PNG with a transparent centre, chosen in the
 *                         Customizer. The image sits above the certificate and
 *                         defines the box; the certificate is inset inside it.
 *   .ks-certframe--css    Fallback ornate gold frame drawn entirely in CSS, used
 *                         when no frame image has been selected yet.
