 * Synthesize the unit-quad corner position and UV from `vertexIndex`.

 *   v = vertexIndex / 2   → 0,0,1,1
 *
 * position = (u - 0.5, v - 0.5, 0), cornerUV = (u, v) — the same
 * corner/UV mapping PlaneGeometry(1, 1) shipped (uv.y = 1 at +y), so
 * atlas remaps and flips behave identically.
 *
 * Pair with `createSynthQuadGeometry()` (index `[0,1,2, 2,1,3]`, CCW).
 * Set `material.positionNode = position` and read `cornerUV` wherever
 * the shader previously read `uv()`.
