//! Layout analysis for Phase 4.
//!
//! This module implements block-level layout analysis including:
//! - Caption classification (caption.rs)
//! - Code block classification (code.rs)
//! - Column label assignment (columns.rs)
//! - Line formation (line.rs)
//! - Readability aggregation (readability.rs)
//! - English wordlist for dict coverage scoring (wordlist.rs)
//! - Text correction pipeline (correction.rs)
//!
//! Phase 4 organizes extracted text into semantic blocks (paragraphs,
//! headings, figures, captions, etc.) based on spatial and font metrics.
