/* Glacier Line — design system for self_travel-4 (Icefields Parkway corridor site)
   Palette grounded in the real corridor: glacial-lake teal, granite grey-black,
   pale ice background, larch-gold autumn accent. Cool-dominant, unlike the
   warm-paper (self_travel-1), navy/brass (self_travel-2) and dusk-warm
   (self_travel-3) systems already in the series. */
