/* ============================================================
   TRAVEL HAVEN — Design Tokens
   Palette: dusk pine, misty fog, tea sage, prayer-flag marigold,
            slate mountain blue. Grounded in Darjeeling/Sikkim tea
            country + trekking-trail vernacular, not template cream/clay.
   Display: Fraunces (warm, literary serif with soft optical curves)
   Body: Public Sans (quiet, legible, humane)
   Utility/eyebrow: Space Mono (ticket-stub, itinerary-stamp feel)
