 * TopNav

 * RHL-019:
 * - App branding
 * - User status placeholder (later: getMe + role/branch info)
 * - Logout button placeholder (later: wired to apiClient.logout)
 * - Theme toggle placeholder (optional; can be replaced by the real ModeToggle)
 *
 * Test/runtime note:
 * - See AppShell.jsx for details why we import React explicitly.
