/**
 * Global search overlay (includes/header-search-overlay.php), opened by
 * the header's search icon on every page.
 *
 * ISOLATION: every rule here is self-contained under the .header-search-*
 * namespace - nothing extends or depends on .eq-*, .dfr-dd__*, or
 * .mobile-nav-drawer* classes, even where a value (border color, shadow, transition timing)
 * happens to match one of those components. The one deliberate exception
 * is reading design tokens from variables.css (var(--color-primary-green),
 * var(--header-height-desktop), etc.) - a plain value substitution, not a
 * shared selector - same convention dfr-dropdown.css itself documents.
 * Desktop panel positioning/shadow mirrors the confirmed dfr-dropdown
 * options-panel spec (Figma "01 - Brand & Design System", node 29:661)
 * since this is the same "panel dropped from a header control" pattern,
 * not a new visual language; the mobile full-sheet treatment mirrors
 * .mobile-nav-drawer's own fixed positioning for the same reason.
 *
 * Requires (must load after): variables.css, header.css.
