 Familiar is a server and the clients that play from it, installed and paired separately. The server
 comes as **Familiar Server** (a Developer ID menu-bar Mac app, source at `desktop/macos/` in this repo)

+  A text test keeps the plist identifier, the `fetch` mode and the registration in step, because a
+  mismatch only shows up on a device, as a crash at launch.
