S4: CRAWLER ships the cave grade that has a frame behind it
The darker rig I preferred (ambient 0.135, exposure 1.45) reads closer to the
spec's near-black cave, but the shared sequencer was pinned on part 12 for the
rest of the session and it could never be shot. What ships is the pair that was
measured: ambient 0.42 / exposure 1.75, at local 3 and local 11, content p50 106
and 98 with crushed 0.0000 against a baseline of p50 2 / crushed 0.46, the
creature's silhouette readable and the letterbox equal top and bottom.
