“Doctors” explaining a 5D ramp with an airport walkway analogy

  "input": {
    "prompt": " Illustration of Dr. Cassian M. Wimple in a lab coat pointing to a diagram that shows an airport moving walkway that bends out of the page into a translucent geometric tunnel labeled “4th/5th Dimension.” Include subtle comedic details: a clipboard-wielding attendant drawn inside the tunnel, and a sign that reads “Gravity Optional.” Style should feel like a magazine spot illustration—clean lines, slightly surreal, but grounded enough to read instantly."
