/* ---------- the CSS rig ----------
 * A second animation path for artwork the WebGL rig is not allowed to touch.
 *
 * A cross-origin image with no CORS header cannot be read into a texture, so it
 * cannot be skinned. It can still be *composed*: two copies of the same image,
 * masked at the neck that the silhouette measurement already found, each rotating
 * about its own joint. The head copy is feathered into the body rather than cut, so
 * a small angle reads as a head moving rather than as two pictures sliding past
 * each other.
 *
 * Two rigid layers, not skinning — no vertex deforms — but it is motion built from
 * this project's own measurements of a still image, which is the point.
