//! Contains the logic for generating Cutter call numbers.
//!
//! The generation logic is split across three submodules:
//! * `common` — configuration ([`CutterConfig`]) and the shared
//!   [`CutterGenerator`] entry-point trait, used by both methods.
//! * `sanborn` — the Cutter-Sanborn three-figure method and its
//!   table-lookup machinery ([`CutterSanbornMethod`], [`UsesTable`]).
//! * `loc` — the Library of Congress method ([`CutterLocMethod`]) and its
//!   digit rules.
//!
//! The public items are re-exported here so callers use
//! `catalog::cutter::generator::{...}` regardless of the internal split.
