//! Integration tests for Data Personality Profiles
//!
//! These tests verify the complete persona system works end-to-end:
//! - Same user ID generates same data across multiple requests
//! - Domain-specific behavior (Finance persona produces banking data)
//! - Trait influence on generated values
//! - Consistency across multiple generations
