/* ARD Identity surface — tokens + components
 *
 * Ported from docs/landing-page-imagery/.../styles/tokens.css (claude.ai/design
 * handoff, 2026-04-25). Defines the brand-level visual register for
 * pre-authenticated marketing + identity surfaces (landing, signup, login,
 * register). Scoped to the .identity-surface root class so it doesn't pollute
 * the rest of the app (which uses the @ard/tokens member/shopper/operator
 * registers via Tailwind).
 *
 * Premium restrained patriotic — NOT the member dramatic register.
