   KROTAR — Marketing Digital section
   Two-column layout: a vertical list of services acts as a selector on the
   left, a single reused card on the right swaps its content on hover/focus.
   Reuses existing tokens only (--color-cyan, --duration-fast, --ease-premium,
   .glass-card, .service-title, .service-desc, .service-link, .ambient-glow) —
   no new colors, fonts or effects.
