/**
 * Notification context — provides a `push()` helper that surfaces
 * toast-style notifications via `react-native-toast-message`.
 *
 * Mount `<NotificationProvider>` somewhere above the components that
 * consume `useNotificationContext()`. The `<Toast />` component itself
 * must be rendered separately in the app root (see
 * `react-native-toast-message` docs).
 *
 * The vault notification provider also bridged a WebSocket service into
 * this context to dispatch server-pushed toasts; that piece is
 * app-specific and not included here. Consumers that need it can build
 * a thin wrapper around this provider.
