/* ==========================================================================
   Uganda Safari Tour — Design Tokens & Base
   Palette grounded in Bwindi forest green + savanna ochre, not a generic
   travel-site default. Fraunces (warmth, character) for display type,
   Inter for body/UI — both loaded at limited weights for performance.
