// SVE binary-op tests. Unlike amd64, SVE has only a handful of (scalable)
// vector types, so there is nothing to generate — these drivers are hand-written
// in the same shape as the generated testXxxBinary helpers. Each loads two input
// windows via the fixed-array API, runs the op, stores the result, and compares
// the lanes the hardware actually populated: the vector's runtime Len() (VL is
// <= the 32-byte backing, enforced at package init).
