+# Manual-only release for now. Once we settle on a tag scheme
+# (e.g. `zarr-metadata/v0.1.0`), this workflow can grow a
+# `release:` or `push: tags:` trigger.
+#
+# Operator picks the target index at dispatch time:
+#   - `pypi`     -> https://pypi.org publishes the version as-declared in
+#                   pyproject.toml. Each version is a single shot — re-runs
+#                   for the same version will be rejected by PyPI.
+#   - `testpypi` -> https://test.pypi.org. The build appends a
+#                   `.dev<run_number>` suffix to the version automatically
+#                   so each test push gets a unique version on TestPyPI.
