// SCAFFOLD — requires NVIDIA hardware to validate; gated behind QGC_HAS_GST_CUDA_GPU_PATH (never defined by CMake yet).
// CUDA/NVMM buffers are routed by exporting the device memory to a DMABuf fd and reusing the DMABuf EGLImage path
// rather than CUDA-GL interop. Enabling this requires CMake gating for gst/cuda/gstcuda.h (gst-plugins-bad CUDA) and a
// Jetson/desktop-NVIDIA test pass.
