   Phones: the stage fills the screen above a compact panel (tabs + one row of cards +
   price bar). Wide screens: stage and a scrolling options column side by side.
   Scene geometry is in photo pixels (the JS sets --f frame, --m mat, --d depth and
   --u = one centimetre on the wall); overlays are in screen pixels.
