# Python wheels for crates/vtracer-py (maturin). Regenerate the skeleton with:
#    maturin generate-ci github -m crates/vtracer-py/Cargo.toml
#
# PREREQUISITE: the framework depends on visioncortex 0.9.0. maturin's Linux
# builds run in manylinux containers where the local `../visioncortex` path is
# not visible, so this workflow only succeeds once visioncortex 0.9.0 is
# published to crates.io and the workspace uses the registry version (not the
# local path).
