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.

h3_prompt_time: the prompt is told how finished it is independently of the
picture, so the model leans on it from the first step instead of treating it
as unreliable while the picture is noise. One extra row through each block's
AdaLN projection, dropped before the result returns. Manual dial only — its
off value sits at the end of its range, not the middle, so the rating loop
cannot explore around it safely.
h3_video_detail: crisper or softer picture with the audio bit-for-bit
unchanged. The final layer is past the last attention pass, so unlike every
other picture control it has no path to the soundtrack.
apply_adaln_gains -> apply_adaln_edits; both block edits share one wrapper.
video_detail joins the rating-learned gains.
