     wrapper caps the box to the column and scrolls horizontally inside it
     instead of breaking the page; it is focusable (tabindex=0 in the markup)
     so keyboard users can reach the clipped columns. A right-edge fade hints

     to the content's right edge (background-attachment:local — scrolls with
     the table), layer 2 is the shadow fixed to the scroll viewport. The cover
