 * The card is the photo: the portrait fills a square, the name sits over it,
 * and role, region and bio come up on hover. Layout, motion and shape only —
 * type, colour and ratio come from custom properties so the cards inherit the
 * site's look rather than imposing one. Set these on .bolts-staff (or :root):
 *
 *   --bolts-ratio         card aspect ratio (square by default)
 *   --bolts-bg            card background, seen behind photos and initials
 *   --bolts-fg            text over the photo
 *   --bolts-accent        stat rules, CTA underline, focus ring
 *   --bolts-detail-bg     hover panel wash
 *   --bolts-stagger-step  how far the offset column drops
