/*
 * sso-popup.css — front-page announcement ("credit") popup.
 *
 * Extracted from the inline <style> in render_credit_popup()
 * (announcement/announcement-popup.php) in Phase 2 (commit f2cde4c) so it can
 * be linted/minified/browser-cached. Enqueued by enqueue_credit_popup_styles().
 *
 * Visibility contract: the markup is always rendered cache-safe with
 * display:none; the inline popup JS flips display, then adds .is-visible via
 * double rAF so the opacity transition below actually runs (see
 * announcement-popup.php for why two frames are needed).
