/* =====================================================================
   GRANDIQUE  —  Maison Collection
   Design system inspired by Hermès Maison / Loro Piana Interiors.
   ---------------------------------------------------------------------
   EDITOR GUARDRAILS (read before modifying):
   1. Whitespace is the product. Sections MUST breathe. Do NOT remove
      vertical padding, do NOT shrink --space-*, do NOT add decorative
      fills to empty areas. Empty space is intentional.
   2. Never exceed --container-max (1440px). Content lives inside
      .container. Hero / full-bleed blocks are the ONLY exceptions.
   3. No more than TWO type weights per screen. No shadows beyond
      --shadow-soft. No gradients except --gradient-fade.
   4. All tunable values are CSS variables below. Add new ones rather
      than hard-coding.
