+# Runs on every push to main.
+# release-please analyses conventional commits since the last release and either:
+#   • creates/updates a "Release PR" that bumps pyproject.toml + CHANGELOG.md, or
+#   • (when that PR is merged) tags the repo and creates a GitHub Release.
+# Only when a GitHub Release is actually created does the publish job run.
