npm create mobile-surfaces What is Mobile Surfaces?
The typed wire format that sits above your ActivityKit bridge. One snapshot shape (LiveSurfaceSnapshot) that your backend, your app, your widget extension, and your APNs payload all agree on. It ships with a contract package, a Node push client, and a catalog of iOS silent-failure modes enforced as CI checks. A reference app wires all of it end to end. Built and maintained by one person as a reference architecture.
