// it — and they win: once the platform claims a touch it cancels ours
// mid-gesture, so a press-and-hold or a drag simply dies. Surfaces that own
// their gesture have to opt out.
//
// What the two classes below cover, precisely:
// - `-webkit-touch-callout: none` stops iOS's long-press callout. WebKit-only:
// it is not a property other engines have, so it is inert everywhere else.
// - `user-select: none` stops the long-press selection on every engine,
// Android included, and stops a drag from painting a selection under the
// cursor. It is inherited, so it reaches every descendant — which is why the
// two classes differ only in whether they apply it unconditionally.
// What neither covers:
// - Chrome for Android's long-press menu on a link or an image. No CSS
// suppresses it; a gesture surface that wraps one needs its own
// `onContextMenu` with `preventDefault()`.
// - The native drag of an `<img>` or `<a>` descendant. `-webkit-user-drag` is
// not inherited and plain divs and buttons are not drag sources, so setting
// it on the surface does nothing — the child itself needs `draggable={false}`.

* gesture itself would paint a selection under the cursor, add `select-none`
* for the duration of the gesture rather than reaching for
* `TOUCH_GESTURE_CLASS`.
*
* `pointer: coarse` describes the *primary* pointer and nothing else, so a

* with a touchscreen keeps the mouse as primary and leaves selection live

// it — and they win: once the platform claims a touch it cancels ours
// mid-gesture, so a press-and-hold or a drag simply dies. Surfaces that own
// their gesture have to opt out.
//
// What the two classes below cover, precisely:
// - `-webkit-touch-callout: none` stops iOS's long-press callout. WebKit-only:
// it is not a property other engines have, so it is inert everywhere else.
// - `user-select: none` stops the long-press selection on every engine,
// Android included, and stops a drag from painting a selection under the
// cursor. It is inherited, so it reaches every descendant — which is why the
// two classes differ only in whether they apply it unconditionally.
// What neither covers:
// - Chrome for Android's long-press menu on a link or an image. No CSS
// suppresses it; a gesture surface that wraps one needs its own
// `onContextMenu` with `preventDefault()`.
// - The native drag of an `<img>` or `<a>` descendant. `-webkit-user-drag` is
// not inherited and plain divs and buttons are not drag sources, so setting
// it on the surface does nothing — the child itself needs `draggable={false}`.

* gesture itself would paint a selection under the cursor, add `select-none`
* for the duration of the gesture rather than reaching for
* `TOUCH_GESTURE_CLASS`.
*

* with a touchscreen keeps the mouse as primary and leaves selection live
