Scene B pushes Scene A off-screen — both move together like pages in a book, with Scene A going from 0 to -100% translateX while Scene B comes from 100% to 0. Uses spring() for physics-based push motion.
Push direction and spring config are configurable. Both scenes are visible simultaneously during the push, creating a connected page-turn feel. A versatile transition for presentations, slideshows, and multi-segment videos.
