//! Error types for the PII library.
//!
//! Errors are grouped by pipeline stage so callers can distinguish:
//! - invalid configuration or profiles
//! - NLP engine failures
//! - recognizer failures
//! - anonymizer failures
//!
//! This keeps error handling explicit and avoids hidden fallbacks.
