/* Home — brand front page (spokardent.cz /).

 * A dedicated, photography-forward layout that deliberately departs from the PDP
 * look: no repeated olive packshot circles. Replicates the spokar.com
 * /pece-o-zuby/ aesthetic — white space, product photos on clean cards and a
 * three-up "why SPOKAR" block — built on the shared design tokens. Loaded only
 * on the front page (functions.php, is_front_page()). Olive stays a thin accent
 * (eyebrow rule, soft icon tile), never a dominant shape.

 * fade the shared transition lost here) while leaving the card's transition free
