/**
 * The creative picker says which creative each one is.
 *
 * Every image creative was labelled by its shape and nothing else, so four
 * square images read "1:1 Image" four times over and the only way to tell them
 * apart was the thumbnail. Shyam, 23 Sep, on seeing it: "there is no preview no
 * info nothing, how does one select a creative".
 *
 * The information existed the whole time. The generator writes a title for
 * every creative - "Women's Light-Wash Cuffed Straight-Leg Jeans" - and the
 * picker never read the column. The shape moved to the hint, where it still
 * answers where this can run without pretending to answer which one it is.
