  finalize() will bind an SSBO of 50090 floats (200360 bytes)
  $colorize_grad_buf for gradient_b reads up to index 50041
  => GPU storage-buffer OOB READ of -45 floats (-180 bytes) past the binding
  On macOS (Graphite/Dawn-Metal default, disable_robustness toggle set in dawn_context_provider.cc), the emitted MSL indexes a raw `device float*` with no bounds check; leaked bytes are rendered as RGBA and readable via getImageData().
