[github-actions]

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset directory. If the changes are user-facing and should cause a version bump, run yarn changeset to track your changes and include them in the next release CHANGELOG. If you are making simple updates to repo configuration, examples, or documentation, you do not need to add a changeset.

[github-actions]

This PR targets a stable release branch (2026-07). Once merged, the change typically also needs to be forward-ported to 2026-10-rc so it ships in the next release.

When you open the forward-port PR, include a line like this in its body so the needs-rc-port label gets removed automatically when that PR merges:

Forward-port of #4677

Accepted formats (comma-separated for multiple):

• #4677
• GH-4677
• 4677
• https://github.com/Shopify/ui-extensions/pull/4677

If a forward-port isn't needed (e.g., the change is stable-only), you can remove the needs-rc-port label manually.
