/**
 * Playwright Global Setup
 *
 * Runs once before all E2E tests. Responsible for:
 * 1. Seeding the database with deterministic E2E test fixtures (via artisan e2e:seed --reset)
 * 2. Authenticating the test user and saving the browser storage state to disk
 *
 * The saved auth state is consumed by the `storageState` fixture in tests/e2e/fixtures/auth.ts,
 * so individual tests start already logged in without repeating the login flow.
