   Storefront — payment modal (Razorpay checkout overlay)
   Used by: index.html (#payment-modal)

   Distinct from .modal-overlay above — different z-index (3000 so it sits
   above generic modals), darker backdrop, more pronounced shadow. The mobile
   scroll-the-overlay treatment is the same as components/modal.css and for
   the same iOS Safari keyboard reason — the guest-checkout form was the
   original repro of that bug.
