// Whether the iOS/iPadOS UI should be in its controller-friendly mode (larger focus targets on
// the host grid, the coverflow library browser instead of the plain grid). A pure function, not a
// singleton: the reactivity comes from callers already observing `GamepadManager.shared` and the
// `DefaultsKey.gamepadUIEnabled` @AppStorage themselves (the same local-read pattern SettingsView
// already uses for GamepadManager), so this stays the single place the two combine without adding
// a second ObservableObject or an environment key nobody else needs.

    /// controller is actually attached (a non-extended-profile device leaves `active` nil, which
    /// keeps the touch UI). A `Bool` rather than the `DiscoveredController` itself: this function's
    /// whole job is the AND, so there's nothing else to inspect, and it keeps the helper testable
    /// without a real `GCController` (which XCTest can't construct).
