• Promotes Websim main, including ci: use the shared verified Sites deployment #5 and the previously merged live-deployment README update.
• Uses the shared workflow pinned to 154eec6262d09d1c034c1984caa4503fd3baca75; the published CLI 0.1.72 installation and --verify flag are confirmed.
• Source CI, clean build and all 19 live-file comparisons pass. The pending diff contains only the deployment workflow and README; no database, app code or credential changes.
• Merge triggers the existing production auto-deploy. Verify the Actions publish job and live files before rolling out to the other apps.
