/// Native UI for the `<sigx-touch-guard>` JSX element on iOS — a plain
/// children-hosting container, shipped for tag symmetry with Android.
///
/// **Why it's a no-op here (#787):** the platform-touch fall-through the tag
/// exists to stop is Android-specific — on Android a Lynx `catchtap` overlay
/// blocks Lynx-level handlers but the raw `MotionEvent` still reaches native
/// views (EditText) underneath, while UIKit's hit-testing already resolves a
/// single touch target, so an overlay's view naturally shadows what's below
/// it. `SigxTouchGuardView.kt` consumes the Android touch stream; this class
/// just hosts the element (and its children) so the same JSX renders on both
/// platforms. `guard-enabled` is accepted and stored but changes nothing.
// Class is NOT marked `@objc` — Swift forbids that on generic subclasses of
// the ObjC lightweight-generic `LynxUI<__covariant V>`. Member-level `@objc`
// annotations still bridge because `LynxUI` itself is `@objc`, so the
// `__lynx_prop_config__*` discovery works.
