   COURSE CARD  (.occ-card)
   Refreshed for the Proten Learning Academy brand: soft elevation
   with a hover lift, a thin brand gradient accent along the top edge,
   and gold/blue in place of the old generic green/orange accents.
   Markup/classes unchanged — templates/course/card.php needs no edits.
