/// 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 size survives re-renders.
///
/// Attach `get_target()` to the caller's markup with the `ref:`
/// attribute, then read `get_width()` / `get_height()` inside a render
/// closure to react to a resize.
///
/// # Returns
///
/// - `UseResizeObserver` - The handle, with `get_target()` returning the
///   [`NodeRef`] and `get_width()` / `get_height()` the reactive size
///   signals.
