/*
 * EU guarantee notice modal
 *
 * Styles for the <dialog> created by eu-guarantee-notice.js.
 * Everything is scoped under the .eu-guarantee-notice-* prefix so it
 * cannot leak into the surrounding theme.
 *
 * Progressive enhancement:
 *  - <dialog> / ::backdrop are Baseline (Chrome 37+, Firefox 98+, Safari 15.4+).
 *  - The open/close animation uses @starting-style and
 *    transition-behavior: allow-discrete. Browsers without support simply
 *    show/hide the dialog instantly, nothing breaks.
