                    // setAttribute so processAttributeChange fires both the C++ setter
                    // (updates _translationY) and the platform transform binder (Android
                    // View.setTranslationY) in one call. On iOS translationY is a composite
                    // part of transformComposite -- setAttribute only marks the composite
                    // dirty; flush() drains it to apply layer.transform same-frame.
