Portrait was drawn upright (tall rect, ribbon on left, arrow up) so the
diagram only made sense while looking at the frame in landscape. The
intended UX is the opposite: the diagram is meant to be read AFTER the
user tilts the frame 90° CW into portrait, at which point it should
look correct.
Render the portrait diagram rotated 90° CCW from upright in the
landscape source — wide rect, ribbon on the bottom, arrow pointing
left. When the user tilts the frame CW, this rotates with the e-ink
content and lands as the canonical portrait view: tall rect, ribbon
on the left, up-arrow pointing up.
Side effect: the landscape diagram looks "rotated" when the frame is
in portrait, which is the same trick in reverse and the desired
behavior.
