- The Windows CNG key and the macOS keychain tag were one name for every profile, so signing out of
the nightly deleted the key the release build's device unlock was sealed to. DeviceKeyNames keeps the
existing name for the default profile and gives every other profile its own; sign-out deletes only
its own key, and a profile sealed before this keeps reading the shared one.
- DevicePinWindow named two palette resources that do not exist and loaded itself with
AvaloniaXamlLoader.Load, which never assigns the named fields, so it threw on construction and no
PIN prompt was ever shown. A layout test now builds it against the real palette.
