# Builds and publishes the `secondwind` Python wheel for every platform. Each leg builds the
# secondwind-ffi cdylib natively for its arch, bundles it into the package, and builds a
# py3-none-<platform> wheel (any Python 3, that OS+arch). Publishes to PyPI on a v* tag.
#
# Verified locally on macOS arm64 (the wheel installs in a clean venv and works); the other legs
# follow the same steps this repo's release.yml already uses, but have not been run cross-platform.
