/* AI Travel Planner — a vintage travel poster.
   Sun-faded cream, deep navy, sunset coral, sea teal and sun yellow. Bebas Neue
   for poster headlines, Work Sans for reading. The search is a ticket, the
   briefing a set of postcards. Every text colour meets WCAG AA (4.5:1) on its
   background in both themes; coral text is only ever set on paper or card. */
