     * ── BRAND TOKEN SSOT POINTER (Track 7, ADR 0052) ──────────────────────────
     * The canonical upstream source for brand color tokens is the CRM repo:
     *   /resources/css/generated/tokens.css  (generated from design-tokens/color.json)
     *   /design-tokens/color.json            (source of truth — edit here, regenerate)
     *
     * CRM canonical mapping (ADR 0052):
     *   --colors-brand / --colors-primary  →  #2D8783  ✓ matches --brand below
     *   --colors-primary-dark              →  #1e5f5c  ✓ matches --brand-dark below
     *   --colors-primary-light             →  #3fa39e  ✓ matches --brand-light below
     *
     * ⚠ BRAND DIVERGENCE — REQUIRES DESIGN DECISION:
     *   --accent: #FF6B35 (orange, used on CTAs and highlights throughout this site)
     *   has NO counterpart in the CRM Track-7 design tokens (color.json / tokens.css).
     *   This is a REAL brand split between the marketing site and the admin/app product.
     *   Do NOT auto-map it to any CRM token — it may intentionally exist only here.
     *   ACTION REQUIRED: design + brand review to decide whether to:
     *     (a) add --accent / orange to CRM design-tokens/color.json (unifies both surfaces)
     *     (b) keep it marketing-site-only (document as intentional divergence in ADR 0052)
     *   Until that decision lands, DO NOT change the #FF6B35 value below.
