/* ════════════════════════════════════════════════════════════════════
   Admin header bar — v3 (2026-05-26)
   ────────────────────────────────────────────────────────────────────
   Redesign goals: cleaner visual hierarchy, modern depth/shadows,
   unified button system (primary/ghost), more prominent Live status,
   and a polished search field. Same DOM IDs/classes so existing JS
   (refreshAdminData, adminLogout, adminSearch, toggleAdminReportsMenu)
   keeps working without a single change.
