/**
 * @eigan/tokens — Eigan design tokens
 *
 * Code encoding of the authoritative brand spec:
 *   docs/brand guidelines/guidelines/Brand.md  (+ Figma "Eigan-Brand-Guidelines")
 * Brand.md is the human source of truth; this file is the source of truth in code.
 * All color values are EXACT per Brand.md — do not approximate.
 *
 * Two tiers:
 *   1. Primitives  (--eigan-*)      the 6 exact named brand colors.
 *   2. Semantic    (--background, --primary, ...)  roles components reference.
 * Components use Tier-2 roles only.
 *
 * Brand discipline baked in: light ground, Midnight Navy text, hairline borders,
 * radius 0-2px (precise, not rounded), NO UI gradients, NO drop shadows.
