/// Bench-only, `bench-internals`-gated access to the production
/// scalar f16/bf16 decoders in [`half_bits`] (lattice#799): `f16_convert_bench`
/// previously carried its own copied scalar decoder instead of calling the
/// migrated production path, so its Criterion numbers said nothing about
/// this crate's actual conversion call sites. This module keeps the crate's
/// default public API unchanged — outside
/// `bench-internals` builds, `half_bits`'s functions stay `pub(crate)`,
/// reachable only from this crate's own load/quantization call sites, the
/// same visibility discipline `forward::metal_qwen35::bench_support` uses
/// for its own bench-only surface.
