/*!
 * static/css/payment.css - backend:payment
 *
 * Styling for the crypto checkout: the public payment page and the admin
 * WALLETS / API CONFIG / TRANSACTIONS panel. Loaded AFTER main.css (and after
 * admin.css on admin pages), so it only adds what those two do not already
 * provide - the .acher-* component classes come from ui:design-system and are
 * never re-implemented here.
 *
 * Every colour goes through the ACHER tokens, with a local fallback in each
 * var() so this file still renders correctly if it is ever loaded on its own.
 *
 * Restrained on purpose: matrix-green is an accent, not a wash. The only glow is
 * on the two things that matter - the amount to send and the countdown.
