It is inherited, so it reaches every descendant — which is why the\n// two classes differ only in whether they apply it unconditionally.\n// What neither covers:\n// - Chrome for Android's long-press menu on a link or an image. No CSS\n// suppresses it; a gesture surface that wraps one needs its own\n// `onContextMenu` with `preventDefault()`.\n// - The native drag of an `` or `` descendant. `-webkit-user-drag` is\n// not inherited and plain divs and buttons are not drag sources, so setting\n// it on the surface does nothing — the child itself needs `draggable={false}`.\n\n/**\n * Classes for a surface that *is* the control: a thumb, a drum, a stage, a\n * handle, a hold button.
