| # GHA workflow which publishes previews of spec PRs to netlify. | |
| # | |
| # We keep this in a separate workflow to the main spec build, because it | |
| # requires access to the Netlify secret. By having it run on `workflow_run`, we | |
| # will only use the workflow definition file on the default branch, so we can | |
| # ensure that the secret can't be exfiltrated. | |
