   Wrapping all nine categories cost three rows, and the sticker grid added
   several more, so the tray pushed everything into a long vertical scroll.
   On a phone both become single swipeable rows instead.

   The reason the original scrolling row failed its audit was not the scroll,
   it was that nothing showed there was more: a phone's overlay scrollbar is
   invisible at rest. So the edges fade only while there is something to
   scroll to, driven by .can-left / .can-right from snowman-ui.js. That is a
   real cue in the direction of travel, and it disappears at each end.

   Scoped to the whole single-column layout, not just portrait phones. A phone
   in landscape is ~844px wide, which sat above a 700px breakpoint and so fell
   back to the wrapped grid -- in the one orientation where vertical space is
   scarcest. Above 900px the layout is two columns and the tray has its own
