/* ============================================================
   Estate — Color tokens
   Warm-neutral, stone-based grayscale + ink-only action.
   The ONLY chroma in the product is the per-property gradient mood
   (atmosphere, never a fill). Semantic green/amber/red appear in status
   only, always as a labelled, tinted chip — never bare color.
   Tier 1 (primitives) → Tier 2 (semantic aliases). Components use Tier 2.
