+// Minimal native-CUDA fast path for Qwen-Image diffusion norm-scale-shift.
+//
+// Supported shape family:
+//   - bf16 activations, B == 1, hidden dim == 3072
+//   - layer norm only, no affine weight/bias
+//   - scale/shift are bf16 row-broadcast tensors ([D], [1,D], or [1,1,D])
+//   - optional residual path uses a bf16 row-broadcast gate
+//
+// All other public-op inputs fall back to the existing CuTe-DSL implementation
+// from the Python dispatcher.
