//! # Error Handling
//!
//! This module defines the error types and result wrappers used throughout the library.
//! It centralizes error handling to provide consistent and meaningful error messages
//! for various failure scenarios that might occur during glTF creation and export.
//!
//! The `GltfError` enum covers errors from various sources including:
//! - I/O operations
//! - JSON serialization/deserialization
//! - Invalid data or parameters
//! - Texture processing issues
//!
//! The module also provides a convenient `Result` type alias for functions
//! that may return a `GltfError`.
