/* cards.css — YouTube-style responsive card grid, shared by every media list
   page (Sách nói / Video / Music video, and any future list). Container is
   .yt-grid; each item is a .yt-card. Cards are flat like YouTube: a rounded
   16:9 thumbnail with a corner badge, a 2-line title, a meta line, and a
   kebab. Each page keeps its OWN kebab menu + JS; only the card shell + the
   .yt-card__kebab trigger styling are shared. */
