  # Exercise the x86 AVX SIMD dispatch path deterministically. Scoped to the
  # x86_64 Linux target only (per-target env, not blanket RUSTFLAGS) so it never
  # touches the aarch64 macOS runner or the thumbv7em no_std cross-build. We use
  # the portable `x86-64-v3` microarch level (SSE2..AVX2+FMA) rather than
  # `target-cpu=native`: `native` lets LLVM enable AVX-512 that some virtualized
  # runners then trap at runtime (SIGILL, even in dependency build scripts).
  # AVX-512 kernels are compile-checked locally, not run in CI.
