/* =====================================================================
   Unified itinerary design — shared across the three itinerary types.

   Provides the hero card, per-type accent theming and the day-number
   badge used by the AI planner (type-a, teal), the Flex chunk planner
   (type-b, purple) and the day planner (type-c, amber).

   A container gets its palette from a `.type-a` / `.type-b` / `.type-c`
   modifier; every rule below reads the accent through CSS custom
   properties so the same markup recolours per type. Component internals
   (chunk cards, day groups, packing, tabs) keep their own per-page CSS
   and simply consume these accent tokens.
