/*
 * newsletter-popup.css — CSB "Get in the Current" signup popup
 * --------------------------------------------------------------
 * Centered modal card on a dimmed overlay. Hard edges (no border-radius
 * anywhere), cream card, terracotta CTA — all values pulled from tokens.css.
 *
 * Component-scoped under .csb-popup-* so it can't collide with the footer
 * .newsletter-* component (template-parts/newsletter.php) or any page CSS.
 *
 * Z-INDEX: .site-header sits at 200 (announcement bar at 250; base.css).
 * The popup must render above the header/nav on every page, so it uses
 * 9000 — comfortably above all in-page chrome, while staying below the
 * third-party cookie-consent modal (.cky-modal, 9999999) so a consent
 * prompt (if ever shown) is never trapped behind it.
