# Trivial metapackage: empty py3-none-any wheel that just pulls libs-base
# and (via the cu13 extra) libs-cu13. No PyPI source release — cutlass-dsl
# ships a PyPI-only metawheel from NVIDIA/cutlass — so packaging the wheel
# directly is byte-equivalent to an empty source.
#
# Always the cu13 path (amd64 + CUDA 13.2 at /opt/cuda); cu12 would need a
# libs-cu12 sibling we haven't packaged. Add a USE flag if a cu12 user emerges.
