//! Shared codec constants, generated fragments, and helper algorithms for the
//! `j2k` workspace.
//!
//! This crate is deliberately small, allocation-free, and `no_std`. Its
//! constants and pure helper algorithms must stay equivalent across CPU,
//! CUDA-Oxide, and Metal backends, but it does not own backend dispatch or
//! kernel-launch policy.
