Apple Folder Expand Interaction

A tap on an iOS home screen folder triggers a smooth expansion transition. The folder icon scales up and morphs into a large container, while the background wallpaper blurs and darkens to focus attention. Inside the folder, the app icons scale up and spread out into a larger grid layout, accompanied by the folder title fading in at the top. Tapping the blurred background reverses the transition with matching spring physics, collapsing the folder back into its original icon state on the home screen.
