/**
 * ❌ BAD EXAMPLE: Direct Entity Reference Across Aggregates
 *
 * Violation: Order aggregate directly imports and uses User entity from User aggregate
 *
 * Problems:
 * 1. Creates tight coupling between aggregates
 * 2. Changes to User entity affect Order aggregate
 * 3. Violates aggregate boundary principles in DDD
 * 4. Makes aggregates not independently modifiable
