   Stick Fighter — fullscreen cabinet theme.
   There is no page: just a black window and one canvas scaled to fill
   it. The canvas backing store is sized to the true pixel density in
   JS, so graphics render smooth and clean at any window size. Every
   menu, button and HUD element you ever see is painted inside it.
