Stamp Collection
three stamps on a dark table. hovering lifts one, clicking brings it to the front and pushes the others behind it, and the print inside a focused stamp slides under its own window.
key insight: the hover lift felt laggy for four separate reasons and only the last one mattered. it is a tween and not a spring, because 14px on a spring is 1.5px a frame and spends most of its time on the last two, and sub-pixel creep reads as sluggish however short the total is.
the paper is an SVG rather than a div with a CSS mask, so its drop-shadow follows the scallops instead of the bounding box. the holes sit centred on the edge line so half of each one bites in, which is the shape a torn perforation has.
