// OCTA STAR — one large octahedron wobbling nose-over: each of the eight
// triangular facets carries the clip on its own flat plane with a per-face
// tint drawn from the palette, so the gem reads as eight slightly different
// screens meeting at hard edges. Pattern taught here: the per-face hash
// rides self.v_attr.w — a hook can reach past its arguments into the
// family's varyings.
