/* fx.css · depth/parallax-layers, shifts the layers of a scene with the pointer · owner: Lizzy East · all rights reserved */

/* Four layers share one frame: the photograph at the back, a glow, a ring, and the
   headline in front. With the pointer, the frame tilts a few degrees and each layer
   slides by its own amount, nearer layers further, so the scene opens up in depth;
   it drifts back to centre when the pointer leaves. The resting composition is the
   finished look: without script, on touch, or with motion off, it is just that. */
