# vendored as a git submodule at vendor/ace-step. The submodule's
# pyproject pins nano-vllm; sys_platform != "darwin" which isn't on PyPI,
# so we list ace-step's deps directly and bypass the pip install of the

# HF Spaces ZeroGPU. Do NOT pin — HF's ZeroGPU build injects its own version
# and a pin causes pip-resolve failure. Locally the `import spaces` in
# app._maybe_spaces_gpu() is wrapped in try/except so absence is fine.
