/**
 * Integration Test: Onboarding Avatar Use Case Orchestration
 * 
 * Tests the orchestration logic of avatar-related Use Cases:
 * - GenerateAvatarUseCase: Generates racing avatar from face photo
 * - ValidateAvatarUseCase: Validates avatar generation parameters
 * - SelectAvatarUseCase: Selects an avatar from generated options
 * - SaveAvatarUseCase: Saves selected avatar to user profile
 * - GetAvatarUseCase: Retrieves user's avatar
 * 
 * Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers, Services)
 * Uses In-Memory adapters for fast, deterministic testing
 * 
 * Focus: Business logic orchestration, NOT UI rendering
