//! Common integer algorithms: number theory basics and combinatorics.
//!
//! All functions in this module operate on `u64` or `u128` integers.
//! They cover GCD/LCM, prime number utilities, combinatorial functions,
//! and digit-based operations.
//!
//! **Canonical implementations live in [`crate::integer`].**
//! This module re-exports them for backward compatibility.
