Every ghost has arms and a tail, and no two share a set of proportions. The head's width-to-height ratio, the eye scale and spacing, and the reach of the arms and tail all change from one to the next. The tail sits well behind the body, so it recedes rather than reading as a fifth limb. Each figure is generated twice from identical geometry: light is the tonal inverse of dark.
The printed measurements are derived from the geometry that renders, not written by hand, and every reach is quoted as a fraction of that ghost's own head width.
