   IMPORTANT: the scanlines live HERE, in CSS at *output* resolution — not in

   into 3-5px stripes and crush the whole image; as a CSS overlay they stay a
   crisp 1px regardless of upscale factor, and cost the renderer nothing.
   `.glass` sits exactly over the canvas (same inset as the frame padding) and
