   # The chained dispatch from `release` lands here as a `workflow_dispatch`

-  # artifact. See "Lifecycle scripts" below for what runs where. Manual

   # recovery uses the same path (Run workflow -> pick a `v*` tag).

+  # uppt/pack's own install step refuses to run without a lockfile, and
+  # this repo has none (`.npmrc` sets `package-lock=false`). No published
+  # package has a `prepack` or `prepare` script, so `npm pack` needs no
+  # dependencies: skip the install and only put Node on PATH.
