// HOOKS CONFIG (per-test, opt-in)
// =============================================================================
//
// Tests pass `hooksConfig` to mount() to override defaults. Shape:
//   {
//     initialRoute?: string,
//     initialQuery?: Record<string, string>,
//     routes?: RouteRecordRaw[],
//     piniaInitialState?: Record<string, Record<string, unknown>>,
//     // injected by mountWithProviders.ts wrapper:
//     notificationMockKey?: string,
//   }
//
// Defaults below render every component with the full Vuexy/Vuetify
// stack. F5 (test-runtime flip) replaces the Vuetify plugin line
// here with PrimeVue and updates the sanity test — that is a ~2-hour
// swap, not a rewrite. Vuetify is INTENTIONAL TEMPORARY STATE in this
// file; do not abstract behind a "UI framework provider" indirection
// because the abstraction would itself need to be removed in F5.
// See dev-docs/ARCH-TESTING.md §7 for the migration timeline.
