/* Token architecture: two tiers.
   1. PRIMITIVES — raw values, named by hue + step (50 lightest → 950 darkest). Never used directly in components.
   2. SEMANTIC   — role-based aliases (brand-*, text-*, surface-*, action-*, border-*, status-*). Components use ONLY these.
   Refined 2026: neutral-first, desaturated navy/coral for an enterprise-calm feel; brand hues unchanged, values tuned. */
