 * Every value falls back to a neutral default, so the gallery looks deliberate

 *
 *   1. Settings > accent colour (writes --coam-accent / --coam-brand)
 *   2. Override any token below in the Customizer's Additional CSS
 *   3. Copy single-coa_report.php into your theme to replace the layout

   Every value below is the matching token from the DualCore Elementor Global
   Kit, so a certificate card and a product card read as the same object on
   the page. Radii are the dc.* family's R_CHIP (10) and R_CARD (14), not the
   plugin's softer 12/18 - the reference's cards are noticeably rounder than
   the trade families and the certificates have to follow. */
