 /**
  * Integration Test: League Creation Use Case Orchestration
- * 
+ *
  * Tests the orchestration logic of league creation-related Use Cases:
  * - CreateLeagueUseCase: Creates a new league with basic information, structure, schedule, scoring, and stewarding configuration
  * - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
  * - Uses In-Memory adapters for fast, deterministic testing
- * 
+ *
  * Focus: Business logic orchestration, NOT UI rendering
