-To re-enable automated releases, remove the `if: false` guard from the

+The workflow carries no push trigger, so there is nothing to disable and no
+guard to remove. Cutting a release means dispatching `build.yml` from the
+Actions tab, or:
+
+```bash
+gh workflow run build.yml
+gh workflow run build.yml -f force_release=true   # within 7 days of the last

+The rate limit refuses a second release inside seven days unless
+`force_release` is set, which is what keeps a stray dispatch from publishing
+twice in a day.
