/**
 * Tests for SliceModal.
 *
 * The modal handles preset selection across three tiers (cloud / local /
 * standard) + enqueueing a slice job. After enqueue success it hands the
 * job_id off to SliceJobTrackerProvider (which lives at app level) and
 * calls onClose. Polling, toasts, and query invalidation all happen in
 * the tracker — not here.
