3/// Reactive state for a hover watcher.
4///
5/// The handle carries the element the hook watches — a [`NodeRef`] the
6/// caller attaches to its own markup — and the signal that reports
7/// whether the pointer is currently over it.
8///
9/// The watcher listens on the document rather than on the element
10/// itself, for the same reason the click-outside watcher does: the
11/// element does not exist while the first render is being built, and a
12/// document listener can then ask whether the pointer's node sits
13/// inside the watched element.
