DESCRIPTION="Fast diffusion-inference kernel library (RoPE + FP8/FP4 quant, binary wheel)"
HOMEPAGE="https://pypi.org/project/comfy-kitchen/"
# No sdist upstream. USE=cuda installs the cp312-abi3 x86_64 manylinux wheel
# (CUDA + Triton kernels); without cuda the py3-none-any wheel -- eager + Triton
# backends, no CUDA -- for CPU/ROCm (its Triton backend rides on dev-python/
# triton-bin's AMD/CPU support).
