/**
 * Golden-path regression spec — session 31444071-a3dc-49bf-90ed-a685217e21a8
 *
 * Covers the five changed workflows:
 *   1. RecoveryRuns/Index — NEW page (empty-state render, no console errors)
 *   2. ContentBriefs/Index + Recommendations/Index + Review/Queue — bulk selection, per-row CTA
 *   3. SharedReport CopyLinkButton — icon flip + safe clipboard wrapper
 *   4. Polling pages — ContentInventory + Admin/Health (visibility-gated, no polling error)
 *   5. RoI Dashboard — renders charts (empty + populated) without console errors
 *
 * == NOTE on public_id routing (migration 2026_05_27_000001) ==
 * All user-facing URLs use ULID public_id. Integer siteId in .seed-data.json
 * is used only for DB lookups. Use resolveSitePublicId() before constructing URLs.
 *
 * Stability: test.describe.configure({ mode: 'serial' }) prevents worker restarts
 * that would re-invoke beforeAll against a freshly --reset seed.
