/* topbar.css — WP4: the two live topbar affordances.
 *
 * 1. Expanding global search — icon-only 32px button that grows to 280px on
 *    hover / focus / typed text, with a sectioned results menu.
 *    Ported VERBATIM from eudr-x sidebar.css:378-539 (gt- → ct-), navy-mapped
 *    per spec-shell §16 (search field bg #222819 → #1a2836; accent tints
 *    rgba(92,120,82,α) → rgba(82,104,120,α); menu shadow forest → navy).
 * 2. Notification bell + panel — ported from eudr-x style.css:506-788 +
 *    sidebar.css:744-753 (gt-topbar reshape), renamed ct-bell-*, navy-mapped.
 *
 * Geometry, clamps, transitions, z-indices and keyframes are kept verbatim.
 * Dark-mode blocks ship here but stay inert until WP7 adds body.dark-mode.
 * The sidebar/topbar CHROME never flips (spec-theme §1.6) — only these two
 * content surfaces (menu + panel) invert in dark mode. */
