     * The `touch-action` this attachment writes on the node — the browser half of
     * the gesture contract. The default `'pan-y'` reserves horizontal dragging for
     * the swipe: the browser pans vertically and leaves the horizontal axis to the
     * handlers below.
     *
     * Pass `null` **while** the node contains a horizontally scrollable box the
     * finger has to reach. Blink intersects `touch-action` down the tree, so a
     * `pan-y` ancestor makes an inner scroller unpannable by touch — the finger
     * would be reserved for a swipe the user never asked for while the content it
     * is trying to reach stays put. Left alone, the browser takes the drag for the
     * scroll and fires `pointercancel`, which this attachment already reads as
     * "not a swipe".
     *
     * `null` is not a way to have both. Measured in Chromium 141 (CDP touch
     * emulation, 390 px, an `overflow: auto` grid inside the swiping node): with
     * `touch-action` left at `auto` a horizontal drag ends in `pointercancel` in
     * every configuration — box overflowing on both axes, on the vertical one
     * only, and not at all — so no swipe is ever reported, whether or not there
     * was anything to scroll. With `pan-y` in force the pointer stream completes,
     * the swipe fires, and the inner box does not pan sideways. Hence: switch this
     * per *measured* overflow (CalendarWeekGrid does exactly that) instead of
     * passing `null` unconditionally, which trades the gesture away everywhere.
     * @default 'pan-y'
