/* Give Phaser a stable, viewport-sized parent. Without an explicit size the
   container shrank to fit the canvas, so when the pixel fonts finished loading
   the layout reflowed and Phaser's cached canvas bounds went stale — pointer
   input then mapped with a vertical bias (buttons felt "shifted up"). A fixed
   full-size parent + Scale.FIT/CENTER_BOTH keeps the bounds correct. */
