   MALDIVES TRAVEL PACKAGE -- design tokens
   Signature: the "depth gradient" -- the same shallow-reef-to-deep-
   atoll colour run used in the hero photography, used again as a
   left-border accent on every comparison card so that colour itself
   tells you whether a package is budget, mid, or luxury tier.
