-// Emits a `New tag: <pkg>@<version>` line for changesets/action so it
-// creates a GitHub Release whose body is the matching CHANGELOG.md entry.
-// Skips emission when the release already exists, so re-runs on main are no-ops.
+// Custom publish step for changesets/action. Single-package repos: the action
+// pushes `v${version}` and creates the GitHub Release at that tag, regardless
+// of what we print (it ignores the package name in `New tag:` output and uses
+// `v${pkg.packageJson.version}` — see changesets/action src/run.ts). It also
+// does NOT create the local tag — `changeset publish` would have, but we
+// replaced that, so we create it here before the action's `git push origin
+// v${version}` runs.
+// Skips when the release already exists, so re-runs on main are no-ops.
