The Orbital Ladder - s to h

One m = 0 orbital for each angular momentum l from 0 to 6, taken at n = l + 1 so every rung is nodeless, giving 1s, 2p, 3d, 4f, 5g, 6h and 7i. Each is a zonal harmonic, so rung l carries l + 1 bands stacked along z. Every rung has its own isovalue at 0.22 of its own maximum |psi| and its own scale, so within-rung proportions are exact while rung-to-rung size is layout. Colour is one accent per rung.
