/**
 * GenerateBriefModal tests — NEW-CI-007: serp_key_available scope preview.
 *
 * The component does not call usePage(), so no Inertia provider is needed.
 * Inertia's `Link` is mocked as a plain anchor in resources/js/test/setup.ts.
 * The global `route()` mock handles `settings.serp` via mockRoutes in setup.ts.
