//! [`crate::int::algos::sqr::sqr_low_fixed::sqr_low_fixed`] and
//! [`crate::int::algos::mul::mul_schoolbook::mul_low_fixed`] kernels. The per-`N`
//! choice lives in [`crate::int::policy::cube`].
//!
//! - [`cube_fused_comba`] — a single fused product-scanning pass for `x³`,
//! the cube analogue of the symmetric comba square. Wired by
//! [`crate::int::policy::cube`] at the `N == 2` tier (it wins there per the
//! `int_cube_eq_ab` A/B); a kept alternative at the other widths where
//! `cube_schoolbook` is faster.
