+Versioning and changelog are handled by [`nx release`](https://nx.dev/docs/features/manage-releases); publishing to npm happens in CI:
 
 ```sh
-pnpm nx release --dry-run   # preview version bump + changelog
-pnpm nx release             # version, changelog, tag, publish to npm
+pnpm nx release --skip-publish --dry-run   # preview version bump + changelog
+pnpm nx release --skip-publish             # version, changelog, tag, GitHub release
 ```
 
-Publishing requires an npm token with access to the `@angular-gsap` scope.
+Publishing the GitHub release triggers `.github/workflows/release.yml`, which
+publishes to npm via [trusted publishing](https://docs.npmjs.com/trusted-publishers)
+(OIDC): no npm token exists anywhere. The trusted publisher is registered on
+the package's npm settings (this repo + `release.yml`).
+
+The very first publish can't use this path (npm only lets you register a
+trusted publisher on a package that already exists), so release 0.1.0 was
+published locally with `pnpm nx release --first-release` and an `npm login`
+session.
