/*
 * Walletio Design System — shared internal UI foundation.
 *
 * Architecture contract:
 * - .wui-* primitives and --wui-* tokens own Walletio's internal visual identity.
 * - Tailwind may coexist for layout/spacing utilities during the gradual migration,
 *   but new components must not recreate WUI colors, typography, states, or shapes.
 * - Business/customer branding stays separate and must never be encoded in --wui-* tokens.
 * - Page-specific CSS (for example walletio-auth.css) may compose these primitives,
 *   but reusable component appearance belongs here.
