+ * Critical User Flows End-to-End Tests
+ *
+ * This test suite proves that all critical business flows work in the actual app:
+ * 1. Public user flow (hero → login)
+ * 2. Authentication flow (login → dashboard)
+ * 3. User dashboard flow
+ * 4. Admin flow (manage users, roles, permissions)
+ * 5. Package management (install, enable, configure)
+ * 6. Navigation and discovery
+ *
+ * These are real end-to-end tests proving the system actually works.
