A full-bleed hero/background that composites a real Amiga-class planar framebuffer image one bitplane at a time: a coarse 2-tone silhouette lands first, then three more binary-weighted planes each add a finer layer of tonal detail on top of it, before the full 16-level image holds and the stack clears to rebuild from plane 0 again.
