/**
 * QI Projects workflow — cross-department team + task management.
 *
 * Tests:
 *   1. Admin creates a project with team from 2+ departments.
 *   2. Tasks assigned to each team member.
 *   3. Team member A (Contact Center) logs in → toggles their task → verified.
 *   4. Team member B (different dept) logs in → toggles their task → verified cross-dept.
 *   5. My Tasks view → team member sees their assigned tasks.
 *   6. Admin exports Excel.
 *   7. Admin closes project.
 *
 * Run headed:
 *   E2E_MAXIMIZED=1 E2E_TIMEOUT=120000 E2E_ACTION_TIMEOUT=12000 \
 *     npx playwright test --headed --project chromium qi-projects-workflow --workers=1
