//! WordCraft document model.
//!
//! A [`Document`] holds the main story (`body`) and secondary stories (`parts`: headers,
//! footers, notes, comments, text boxes). A story is a list of [`Block`]s: paragraphs and tables;
//! table cells hold block lists of their own. Blocks, the style sheet and the list definitions
//! are `Arc`-shared, so cloning a document is cheap (undo snapshots, handing a frozen copy to the
//! renderer) and edits copy only what they touch (`Arc::make_mut`).
//!
//! Positions ([`Pos`]) name a story, a [`Path`] to a paragraph and a byte offset in it. Paths
//! compare in document order.
