// `Inf - Inf = NaN` — neither returns `0.0`. `RightIdentity { element:
// 0 }` holds for all finite and infinite inputs, and holds bit-exactly
// for the NaN payload (`NaN - 0 = NaN` preserves the payload).
// Per audit `primitive-laws-kimi-AUDIT`.

// WGSL lowering marker for `primitive.float.f32_sub`.
//
// Not a stub: this is a zero-overhead Category A marker. `F32Sub::program`
// builds concrete IR through `core/src/ops/primitive/binary_f32_program.rs`;
// `core/src/lower/wgsl/expr.rs::emit_binop` emits WGSL.
// `core/tests/conformance.rs::conformance_all_primitives` verifies
// lowered GPU bytes are bit-exact against the conform CPU reference.
//
// ```wgsl
// _vyre_store_out(idx, (_vyre_load_a(idx) - _vyre_load_b(idx)));
// ```
