In portrait orientation the cable/ribbon is on the left, so the
physical 'up' edge of the hung frame corresponds to the right side
of the rendered diagram — not the top. Swap the up-arrow inside the
portrait screen for a right-arrow so the diagram actually shows the
user which edge will be up when they hang the frame.
Landscape diagram is unchanged (cable on bottom → up is up).
