AppShellScope class

App-level chrome injected into the design-system shell from the host app.

The design system's StandardScaffold is presentational and must not depend on application services (auth, routing, API clients). Apps inject app-specific chrome — such as the user profile menu — by wrapping their shell subtree in an AppShellScope. The scaffold then reads it via AppShellScope.maybeOf.

Provide it once near the app root, e.g.:

AppShellScope(
  profileMenu: const UserProfileMenu(),
  child: child,
)
