/* ================================================================
   ARCLUNE — POLAR NIGHT / ICE SILVER DESIGN SYSTEM
   ----------------------------------------------------------------
   Design rationale:
   1) Navy mirrors the supplied logo and communicates cold-chain trust.
   2) Cyan/silver accents echo the crescent + snowflake without copying it.
   3) The page avoids the old "hero → ribbon → grid → metrics → footer" stack.
      Instead, it uses floating editorial layers, a moving flow band, a product
      matrix, an app-like trade module and an integrated contact/map sculpture.
   4) Spacing and type are tuned around the requested 1085 x 1451 visual density,
      while clamp() keeps the same hierarchy on laptop and mobile screens.
