/* NIGHT ECHO — UI shell
   Two builds share one stylesheet:
     body.desktop  fixed 960x544 frame, keyboard + mouse HUD
     body.mobile   canvas matches the device aspect, touch controls
   Everything inside #stage is authored in canvas pixels; the stage itself is
   transform-scaled to fill the window, so both builds stay pixel-consistent. */
