# Trivial meta-wheel — empty package whose entire purpose is to pull
# cuda-bindings + cuda-pathfinder via runtime deps. Source is just
# pyproject.toml in the cuda-python/ subdir of NVIDIA/cuda-python with
# no Python code; packaging the wheel directly is exactly equivalent
# and avoids carrying the monorepo tarball for an empty payload.
