   GEOMETRY
   Microsoft's WP8 Tile spec, verbatim, at WXGA:
       small   159 × 159
       medium  336 × 336
       wide    691 × 336
   Two smalls plus a gutter make a medium, so the gutter is 18px
   (2·159 + 18 = 336), and four smalls plus three gutters make the grid
   (4·159 + 3·18 = 690 ≈ 691). So Start is a 4-column grid of 159px units
   with an 18px gap - everything below is that ratio expressed in vw, which
   keeps the proportions identical at any phone width.
   ========================================================================== */

  /* 18 / 768 = 2.34vw. Windows Phone put a wide margin on the right of Start
     to house the → arrow; with the arrow replaced by a swipe there's nothing
     to leave room for, so the same total margin is split evenly and the grid
     sits centred. */
