/**
 * User Response DTO
 *
 * DDD Pattern: Data Transfer Object
 * - No business logic
 * - Presentation layer data structure
 * - Protects domain from external changes
 *
 * SOLID Principles:
 * - SRP: only data transfer
 * - ISP: client-specific interface
 *
 * Clean Architecture:
 * - Application layer DTO
 * - Maps to/from domain
 * - API contracts
 *
 * Benefits:
 * - Domain entity isolation
 * - API versioning
 * - Client-specific data
