/* Playnesta shell stylesheet for Click Sprint (Playnesta-original, MIT).
   No sprites, fonts, images or network assets: the pad, the ripples and the
   bar are plain elements. The layout has to fit both production stages
   (894x670 desktop and 348x261 phone) with no overflow in either axis, so the
   pad is the only element that grows and everything else is a fixed row. */
