/**
 * COD form — the shared field + CTA component.
 *
 * Single source of truth for the cash-on-delivery form's look. Two consumers:
 *
 *   inc/woocommerce/checkout/       single-product Quick Checkout  (the master)
 *   inc/woocommerce/checkout-page/  the Checkout COD page
 *
 * Every value here was lifted verbatim out of the product form's sheet, which
 * is the design reference — the checkout page used to carry its own, slightly
 * different, copy of the same idea (taller inputs, borderless icon column,
 * labels above each field) and the two drifted apart visually. Nothing is
 * redesigned here; the rules simply moved so both pages load the same bytes.
 *
 * Selectors are deliberately unscoped: the product form nests these classes
 * under .opsim-modular-checkout-wrapper, the checkout page does not, and the
 * classes appear nowhere else in the theme. This sheet is only ever enqueued
 * on those two pages.
 *
 * Adding a rule here changes BOTH forms. Anything that should apply to only
 * one of them belongs in that module's own sheet.
