/// Behaves like `HookContext::use_hook` - the same handle is returned on
/// every render at the same hook index, so the observer is created once
/// and the visibility survives re-renders.
///
/// Attach `get_target()` to the caller's markup with the `ref:`
/// attribute, then read `get_visible()` inside a render closure to
/// react to the element entering or leaving the viewport.
///
/// # Returns
///
/// - `UseIntersectionObserver` - The handle, with `get_target()`
///   returning the [`NodeRef`] and `get_visible()` the reactive
///   `Signal<bool>`.
