/// A generic left-side mobile drawer with overlay, aligned with common
/// component libraries and the euv example's overlay-stack behaviour.
///
/// The drawer and overlay are always mounted and slide/fade via reactive
/// classes driven by the caller-owned `open` signal; clicking the overlay
/// closes the drawer through [`Router::overlay_stack_close`], so the browser
/// / system back gesture history entry pushed when the drawer opened is
/// consumed and stays in sync.
///
/// # Arguments
///
/// - `VirtualNode<EuvDrawerProps>` - The props node containing the open signal.
///
/// # Returns
///
/// - `VirtualNode` - The drawer virtual DOM tree.
