/// attached once and the hover state survives re-renders.

/// Attach `get_target()` to the caller's markup with the `ref:`
/// attribute, then read `get_hovered()` inside a render closure to
/// react to the pointer entering or leaving.
///
/// # Returns
///
/// - `UseHover` - The handle, with `get_target()` returning the
///   [`NodeRef`] and `get_hovered()` the reactive `Signal<bool>`.
