 * ExplorerPageShell

 * Consistent framing for all Explorer pages:
 * - Title + optional description
 * - Breadcrumbs as ReactNode (supports dropdown composition)
 * - Optional actions (refresh, etc.)
 *
 * The shell intentionally does not "build" breadcrumbs to avoid tight coupling
 * and to keep dropdown variants easy and clean.
 *

 *   title: string,
 *   description?: string|null,
 *   breadcrumbs?: React.ReactNode,
 *   actions?: React.ReactNode,
