/**
 * Epic 1: Authentication & User Management
 * Acceptance Test: User Registration
 *
 * User Story: As a new user, I want to register for an account so that I can participate in tournaments and track my games
 *
 * Acceptance Criteria:
 * - Registration form with name, email, password, password confirmation
 * - Email validation and uniqueness check
 * - Password strength requirements (8+ chars, uppercase, lowercase, number, special char)
 * - Account confirmation via email (placeholder)
 * - Auto-create player profile upon registration
