//! Scalar reference implementations for the H.264 hot kernels.
//!
//! Always compiled, used as the fallback on any target and as the
//! oracle for `simd::tests::*_matches_scalar`. These wrap the existing
//! `inter_pred` entry points unchanged so we have a stable bit-exact
//! reference while we develop the chunked/portable variants.
