   frame and doesn't have room to breathe on a phone-width viewport (or a
   short phone-landscape viewport), so home.js skips the animation
   entirely in either case and just appends tiles in document order;
   this CSS lays them out as a simple two-column grid that scrolls
   normally with the page. Keep this query in sync with MOBILE_QUERY in
