| # Manually triggered from the Actions tab. Pick how to bump; the target version | |
| # is computed from the CURRENT version at run time (nothing is hard-coded). This | |
| # sets every package in lockstep (lerna fixed mode) and opens a "Release X.Y.Z" | |
| # PR that only touches lerna.json + package.json files. Merging that PR and | |
| # publishing a GitHub Release is what actually ships to npm. | |

| Automated version bump to **`${{ steps.bump.outputs.version }}`**. | |
| - Triggered by @${{ github.actor }} via `workflow_dispatch` (bump: `${{ inputs.bump }}`). | |
| - On publishing a GitHub Release, this will go to npm under dist-tag **`${{ steps.bump.outputs.dist_tag }}`**. | |
| **Next steps:** review & merge, then cut the GitHub Release. |
