“The commission is allowing for a custom-made podium, which will accommodate the difference in stature”
I take that to mean either a shorter platform or a custom built platform that she ramps up to. If they don’t spell it out, then I’m sure she’ll go with the second.
I’m guessing a shorter podium for her and the camera angles set to disguise the fact. One thing a person must do during a 90 minute debate is move around a bit, up to the podium, back from it, side-to-side, etc. Remaining inert would be too dangerous to her circulatory system ... and her cankles could swell to noticeable size even under her pantlegs over her tiny feet.
