-`bin/publish.mjs` implements it. The ordering is the point: everything fallible runs before anything irreversible, and npm is published before git is tagged, so a tag can never point at a version nobody can install. There is no rollback — every step is idempotent, so an interrupted release is resumed by re-running it. Tags are per package (`datocms-structured-text-utils@6.1.0`); the historical `vX.Y.Z` tags stay where they are.

+Everything that acts on **this repository** rather than shipping to a user.
+
+`packages/*` is the product. This is the machinery that turns the product into
+releases: it reads the repo, writes into it, and produces something outside it —
+a version bump, a changelog, a commit, a tag, an npm package, a GitHub release.
+Nothing in here is published, and nothing in here is imported by code that is.
