   All positions are in design-canvas pixels (desktop canvas 1440 × 1024,
   portrait canvas 430 × 860). The canvas is scaled to the viewport with
   --s; --bx / --by are the letterbox bleed (in canvas px) on each side.
   Elements that belong to the viewport edges subtract the bleed so they
   sit at a fixed gutter from the real edge on every screen.
