//! BigNum implementation for arbitrary-precision integer arithmetic.
//!
//! The public types in this module are value-level helpers. They do not define
//! the GP TEE `TEE_BigInt` memory layout; `rust-libutee` owns that ABI boundary
//! and converts it to these types before doing arithmetic.
//!
//! `TeeBigNum` is an unsigned wrapper used by kernel crypto object code.
//! `TeeBigInt` is a signed facade used by the GP TEE arithmetic API. Signed
//! division returns a quotient truncated toward zero and a remainder with the
//! dividend sign; `modulo` normalizes the result to a non-negative residue.
//!
//! Several operations use `crypto-bigint` variable-time APIs. Callers should not
//! treat this module as a constant-time primitive for secret-dependent control
//! flow without auditing the exact operation being used.
