# Originally generated by maturin v1.8.6 (maturin generate-ci), then customized:
# this workflow (the cross-arch wheel/sdist matrix + publish) runs ONLY on release
# tags and manual dispatch — NOT on every PR/merge, which is slow and rarely
# catches anything a logic change would break. Per-PR validation lives in
# rust-ci.yml, whose `python` job builds the pyo3 extension via maturin develop +
# pytest, so binding breakage is still caught before merge. The tag build gates
# publish, so nothing broken ever ships; use `workflow_dispatch` for a full-matrix
# dry run before tagging. Regenerating with maturin will drop these customizations.
