1/**
2 * KeepService — framework-agnostic job "keep" (favorite) logic.
3 * Mirrors the Angular User.addFavorite/favoriteDelete + LocalKeepService +
4 * NotificationsService behaviour so Vue pages behave identically.
5 *
6 * window.KeepService.toggle(jobId, currentlyKept) -> Promise<boolean> (new state)
