Three lessons worth more than the scenes: a slow axis has to move a large
low-frequency area or the camera's own drift beats it, whole-frame luminance on
the kick is the strobe the flash gate exists for and it arrives by accident, and
a style trait expressed only as grain measures as no style at all.

Even spread across families is not useful spread — casting disqualifies any
scene that misses a signature trait, so space and shape are worth more than
another entry in a full family. Each scene is specced against the neighbour it
must not resemble, because that is the gate with the numeric floor.
