  /* Explicit size, not just inset:0 (W0.6): a <canvas> is a replaced element
     whose own width/height attributes can win the layout box over inset
     alone. Three.js's renderer.setSize() writes those attributes every
     resize; without this, that feeds back into the canvas's own layout
     size and compounds on every resize event (observed ballooning a
     1200x751 viewport to 76800x48064 over a handful of resizes, which
     silently broke rendering of small scene objects). The solo game entries
     (e.g. games/windward/index.html's #game) already pin size this way. */
