/* ============================================================
   MeBiz Storefront — Checkout STANDALONE brandeable
   Réplica fiel del checkout de ticketmax.org (/pagos/), pero:
   - sin WordPress/WooCommerce (habla con mebiz-store/v1/checkout)
   - brandeable por sitio: el acento morado de TicketMax se movió a
     variables CSS (--brand / --brand-2 / --brand-rgb / --brand-tint).
     Cada marca solo redefine esas variables en :root (o inline).
   Base: ticketmax/assets/css/standalone-checkout.css (identidad
   visual idéntica: topbar+progreso, wizard 2 pasos, sidebar resumen,
   cupón, términos, trust, overlay de procesando).
   ============================================================ */
