/* =============================================================================
 * gold.css — Conceptual Health® Gold Standard design system
 *
 * The single shared visual system for the gold site rewrite. The Standard
 * page uses it; Home, Verify, and Domains pages reuse it. Self-contained
 * (no external CDNs / fonts — CSP-safe), responsive, fast.
 *
 * Aesthetic of record: the calm holding-page family —
 *   deep green-black grounds (#0c1612 / #16201b), cream daylight sections
 *   (#faf9f6), emerald (#2ed5a0) as the single live/verify accent, forest
 *   green (#1f7a52) for quiet labels, warm gold (#b08d3c) for "pending".
 * Tokens are aligned 1:1 with ch-site.css so the two systems flow as one.
