  Applied via JS: WallDisplay.applyPixelShift(elementId, x, y)
  The .wdp-root wrapper transitions its transform smoothly (2s ease-in-out)
  so the shift is imperceptible to viewers but effective against OLED retention.
  Max shift = ±3px — enough to prevent static pixels, invisible at TV distance.
