Video description: A 5-second video shows a collection grid of different micro interactions. The top left tile reads “Hang tight.” and then “Almost done.” while a dashed line in ebay colors animates below. To the right is a tile with 5 icons: home, profile, search, notification, and selling. A blue indicator hovers over each icon and the icons have a popping wiggle motion. The bottom left tile shows the filled AI icon centered that swipes to the left and gets smaller, while a chat bubble appears with a typing indicator and a message. To the right of that is a bright green illustrated tile with a handbag and watch in a box. There is a white button reading “Luxury”. The illustration has a pop motion and a black outline appears around it. The button turns black and in white reads a checkmark and “Luxury”. The last tile is a shopping cart icon in a white circle on a pink background. The icon has a popping motion and a small red circle with “1” appears on its upper right. The popping motion happens as the red circle changes from “1” to “2” to “3”.
