/**
 * Workflow Verification — b0705e9a-502c-4020-b41e-e298ec46b64b
 *
 * Golden-path + sad-path spec for three changed UI files:
 *   - Components/Bulk/ScopeCostModal.tsx  (shared bulk-AI dispatch modal)
 *   - Pages/OpportunityMap/Index.tsx      (uses ScopeCostModal for draftable recs)
 *   - Pages/Sites/ContentInventory.tsx   (uses ScopeCostModal for WP-post batching)
 *
 * Scope derived from diff (no SUCCESS_CRITERIA / WORKFLOW_BLAST_RADIUS provided).
 *
 * == Public-ID routing note ==
 * All user-facing site URLs use the ULID public_id (HasPublicId trait, migration
 * 2026_05_27_000001). This spec resolves ULIDs via artisan tinker in beforeAll.
 * Integer IDs from seed-data.json are used only for DB lookups, never in URLs.
 *
 * == Coverage ==
 * 1. ContentInventory — loads, filter bar works, batch-selection bar appears,
 *    ScopeCostModal opens and handles estimate-error gracefully.
 * 2. OpportunityMap — loads, opportunity cards visible, filter type tab works,
 *    ScopeCostModal path present (modal only opens when draftable recs selected).
 * 3. Sad paths — empty filter state, unauthenticated access, console errors
 *    checked after every navigation.
