Module slide 

Slide — wraps a child and slides it in or out from a chosen edge when an external Signal<bool> toggles. Common patterns: drawers, snackbars, side panels, banner notifications.

let visible = ctx.signal(false);
ctx.add(
    Slide::new(visible.clone())
        .from(SlideEdge::Bottom)
        .child(snackbar_content),
);
// ...elsewhere:
visible.set(true);   // slides in from below

Layout semantics

Slide’s own slot stays in its laid-out position; the child is translated within the slot via place_children. The wrapper clips so a sliding-in child doesn’t bleed past the slot edges. The wrapper reports the child’s full natural size at all progress values — siblings don’t reflow as the child slides.

For a “slide + fade” effect (notification snackbar), wrap the child in Fade before passing it to Slide:

let _w = Slide::new(visible.clone())
    .from(SlideEdge::Bottom)
    .child(Fade::new(visible).child(snackbar_content));

Reduced motion

Honours prefers-reduced-motion: snaps the child instantly into or out of position instead of tweening.
