/*
 * Shared storefront credit-card input.
 *
 * Used by every payment plugin that still collects raw card data on our own page
 * (Manual, AuthorizeNet, AkbankPos, GarantiPos, ParamPos, Iyzico, PayTR, Tranzila).
 * The markup contract and the behaviour live in wwwroot/js/opus-credit-card.js.
 *
 * Plain CSS on purpose: opus-theme.css is a generated Tailwind bundle and is
 * gitignored, so component styles that must survive without a css build live here
 * and are linked from Views/Shared/Head.cshtml. All colours resolve through the
 * --opus-* token layer, so tenant theme overrides repaint this too.
