Description
Where is the code that quantizes the fp32 mma output to nvfp4 for this kernel: https://github.com/NVIDIA/cutlass/blob/main/examples/72_blackwell_narrow_precision_gemm/72b_blackwell_nvfp4_nvfp4_gemm.cu ?

Research direction
Start by reading examples/72_blackwell_narrow_precision_gemm/72b_blackwell_nvfp4_nvfp4_gemm.cu and trace the fp32 MMA output through the kernel. Identify where fp32-to-nvfp4 quantization occurs, or document that it is handled elsewhere; completion requires a precise code location and explanation.
