   PROJECT CAROUSEL — "the card catalog"
   A library index-tab rail sits beside one full

   along its existing visual/body seam: the photo
   half is pulled up off the top, the body half is
   pulled down off the bottom, like yanking a card
   out of a drawer — and the next card slides in
   from the opposite edges to fill the gap.
