/* Leo's mini app, after Muse's look: dark rounded cards, one blue main button per card, quiet text for the
   rest. One 4/8px spacing scale; 16px card padding, 12px between cards. Every text colour passes WCAG AA
   on the surface it sits on (ratios noted). No gradients, no images but Amazon's product photos. */
