/*
 * Storefront checkout — Phase 2 native (Tabler) re-skin.  (Twisti, 2026-09-04)
 *
 * Linked by the two PAGE templates in catalog/view/template/checkout/
 * (cart.twig, checkout.twig). The FRAGMENTS (cart_list, register,
 * payment_address, shipping_address, shipping_method, payment_method, confirm)
 * are AJAX-loaded into those pages and rely on this file being present there.
 *
 * Scope rule: this file only adds what the shell (store.css / app.css /
 * uix.min.css) does NOT provide. It is screen-scoped: every class starts with
 * `chk-`, and the few selectors that reach into stock ids (#checkout-payment,
 * #output-cart) do so only to style markup the payment/total extensions inject
 * and that this theme cannot rewrite. No `!important`; nothing here outranks
 * a Tabler `.btn-*` variant (those are (0,1,0) and set their own colour).
 *
 * Tokens come from app.css (--app-*) and store.css (--store-*). Layout is
 * logical-property / grid based so it survives RTL.
 *
 * JS contract (frozen — see the templates): every container id, form id,
 * input name and data-oc-* attribute is stock; this file never depends on a
 * class the fragment scripts do not already emit.
