Measured on a rental: 0.8 gave more contrast and 1.2 less, and 1.15 was
nearly inert.
The layer computes norm(x) * (1 + scale) + shift, and the first build
multiplied `scale` itself. H3's scale is negative, so raising the dial shrank
(1 + scale) and the control inverted. Scaling the whole (1 + scale) term
instead is monotone in magnitude whichever sign a checkpoint carries, so
"above 1.0 is more" holds by construction rather than by luck. shift is still
left alone — it is the bias.
