/* ==========================================================================
   KROTAR — Delivery section, interactive area selector
   Same pattern as assets/css/marketing-digital.css (independent file/classes
   on purpose, so neither section's styles can affect the other): a vertical
   list of areas 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) — no new colors, fonts or effects. No
   ambient-glow here on purpose: reviews.css already establishes this section
   as deliberately "sober... no dominant blue wash", so this redesign keeps
   that same quieter lighting rather than importing Marketing Digital's glow.
