//! Product Catalog Engine (PCM) Framework
//!
//! The Product Catalog Engine is the heart of the BSS, providing business agility
//! through efficient management of pricing, eligibility, and bundling rules.
//!
//! This framework abstracts the complexity of:
//! - Pricing rules and calculations
//! - Product eligibility validation
//! - Bundling and product relationships
//! - Catalog versioning and lifecycle management
//!
//! Built with Rust's safety guarantees to prevent costly billing errors.
