A deck that handles like physical cards: every card rides a continuous slot spring (k=90, d=12) and sending the front card drives a 210px side arc, a 150px z-lift and a full rotateY flip that reveals a patterned back before it tucks in behind. Drag, tap, prev/next buttons and arrow keys all drive one state, with an aria-live announcement per shuffle and instant reordering under reduced motion.
