Cross-section reveals nested scales from atoms to galaxies.

variables ::=
m = magnitude-progression clarity (each shell is clearly a bigger order)
r = scale-ratio fidelity          (relative shell sizes map to magnitudes)
o = nesting recognizability       (the containment reads instantly)
s = shell distinctness            (each layer is separable and labeled)
d = peel/cutaway clarity          (you can see into the nesting)
l = label readability
f = factual restraint
p = premium render polish

maximize ::=
j = 0.20m + 0.18r + 0.14o + 0.14s + 0.12d + 0.08l + 0.08f + 0.06p

constraints ::=
m >= 0.90   // the order-of-magnitude jumps read
r >= 0.88   // relative sizes track the data
o >= 0.88   // the nesting is obvious
s >= 0.86   // shells stay separable
d >= 0.84   // you can see inward
l >= 0.86
f >= 0.94   // no invented magnitudes
p >= 0.86

forbidden ::=
  invented magnitudes, fake order-of-magnitude jumps, hallucinated scale values
  shells implying true-to-scale when ratios are compressed without a "log / compressed scale" note, decorative rings with no magnitude meaning, missing scale labels
  shells blending together, illegible magnitude labels, cluttered core
