/**
 * global-setup.ts — Playwright globalSetup: /health readiness gate + deterministic DB seed
 *
 * Runs ONCE before any spec file. Plain Node.js only (fetch + mysql2/promise).
 * No @playwright/test imports — globalSetup runs outside the worker context (Pitfall 2).
 *
 * Step 1 (D-08 readiness gate):
 *   Poll baseURL/health until 200 OK (60s timeout, fail fast on expiry).
 *
 * Step 2 (D-05/D-06/D-07 deterministic seed):
 *   TRUNCATE → INSERT seed rows onto calendar_id=10 + lists for user_id=1.
 *   Idempotent: truncate-first guarantees the same row counts on every run.
 *
 * Anchor values the specs assert on — do NOT change without updating the specs:
 *   - calendar_events.title  = 'Seeded Test Event'
 *   - lists.name             = 'E2E Grocery List'
 *   - list_items.text        = 'Milk', 'Eggs'
 *
 * Run:
 *   pnpm --filter @familysync/pwa test:e2e
