//! Document types - pure data structures for document tree representation.
//!
//! This module contains the core types that represent hierarchical documents.
//! These types have no dependencies on compile or retrieval logic.
//!
//! # Types
//!
//! - [`TreeNode`] - A node in the document tree
//! - [`DocumentTree`] - Arena-based tree structure
//! - [`NodeId`] - Unique identifier for tree nodes
//! - [`TocView`] - Table of Contents generator
//! - [`StructureNode`] - JSON export structure
//! - [`NodeReference`] - In-document reference (e.g., "see Appendix G")
//! - [`RefType`] - Type of reference (Section, Appendix, Table, etc.)
