/* ---------- the crew on the graph paper ----------
 *
 * A facade scaffold going up against a building behind the page, slowly, and
 * coming down again. Meant to be noticed once and then ignored, so everything
 * here is tuned toward "texture" and away from "animation": low contrast,
 * long durations, no motion fast enough to catch the eye while somebody is
 * reading a number off a quote.
 *
 * z-index -1 is the whole clipping strategy. The .sheet cards are opaque, so
 * they cover this completely and it survives only in the gutters -- the grid
 * area. Nothing here needs to know where the content is.
 *
 * The weight hierarchy is doing as much work as the geometry. The building is
 * faintest, the inner row of standards sits behind the outer, and the crew is
 * the darkest thing on the layer -- which is how depth reads at this opacity
 * without a single gradient.
 *
 * The split between `sw-raise` and `sw-fade` is not cosmetic. A CSS transform
 * animation overrides an element's SVG transform attribute, so anything that
 * has been *placed* -- every worker, the load on the rope -- may only be
 * animated on opacity, and gets a nested group when it needs to move. Members
 * are bare lines with no placement of their own, so they can also settle into
 * position. Mixing the two drops the crew to the origin, silently.
