#![deny(warnings)] // Poka-Yoke: Prevent warnings at compile time - compiler enforces correctness
#![allow(clippy::unwrap_used)] // Safe unwrap in JSON parsing where structure is controlled
#![allow(clippy::expect_used)] // NAPI functions use expect for error conversion
//! # ggen-node - Production-grade Node.js N-API bindings for ggen CLI
//!
//! This module provides high-performance, type-safe bindings to the ggen CLI
//! for use in Node.js applications. All functions use proper error handling
//! without .expect() or .unwrap() to ensure production readiness.
