# Python wheels for crates/vtracer-py (maturin). Regenerate the skeleton with:
#    maturin generate-ci github -m crates/vtracer-py/Cargo.toml
name: Python

# Wheel builds are heavy (full platform matrix), so they run only on release
# tags and on-demand — not on every push/PR. Rust/wasm/Node CI (rust.yml) still
# gates ordinary commits.
