component_model 0.17.0

//! Integration tests for `ComponentModel` derive macro
//!
//! ## Test Matrix: Integration and Complex Scenarios
//!
//! ### Test Factors
//! - **Struct Complexity** : Simple, Complex, Nested, Generic
//! - **Type Mixing** : Popular only, Basic only, Mixed popular+basic
//! - **Real-world Usage** : Configuration structs, Builder patterns, Data models
//! - **Default Behavior** : Auto-derivable, Custom implementations
//!
//! ### Test Combinations
//!
//! | ID    | Complexity | Type Mixing    | Usage Pattern   | Default Behavior | Expected Behavior |
//! |-------|------------|----------------|----------------|------------------|-------------------|
//! | TIC01 | Complex    | Mixed          | Configuration  | Custom Default   | All assignment styles work |
//! | TIC02 | Simple     | Popular only   | Data model     | Custom Default   | Type-specific assignments work |
//! | TIC03 | Generic    | Basic only     | Builder        | Auto Default     | Generic implementations work |
//! | TIC04 | Nested     | Mixed          | Hierarchical   | Mixed Default    | Nested assignment works |
//! | TIC05 | Real-world | All types      | App config     | Custom Default   | Production-ready usage |
