+# Labels each PR with its conventional-commit type (feat, fix, docs, perf,
+# refactor, chore) derived from the PR title. These labels drive the changelog
+# categories in .github/release.yml when release-please generates notes.
+# chore is labeled but excluded from the changelog (see .github/release.yml),
+# preserving the previous "chore hidden" behavior.
