| # On-demand preview builds — NOT published to npm. | |
| # | |
| # Publishes @juspay/rescript-blend to pkg.pr.new and prints an installable URL | |
| # you can drop into a consumer (e.g. `yarn add https://pkg.pr.new/...`) to test a | |
| # branch's exact build before it is ever released. This is the producer side of | |
| # the `pkg.pr.new` URL that the sync-bindings workflow already accepts as input. | |
| # | |
| # Trigger from the Actions tab ("Run workflow" → pick a branch), or: | |
| # gh workflow run preview.yml --ref <branch> | |
| # | |
| # Prerequisite (one-time, org admin): install the pkg.pr.new GitHub App on this | |
| # repo — https://github.com/apps/pkg-pr-new. No npm token/secret is needed; | |
| # pkg.pr.new authenticates via the App plus this workflow's OIDC token. | |
