/**
 * Build the shared per-batch envelope geometry (tight-mesh Option A):
 * the convex hull of every registered frame polygon in the atlas, in
 * unit-quad local space, with corner UVs derived from position — the
 * same `local + 0.5` mapping the synth quad uses, so the shader's
 * flip/atlas remap applies unchanged.
 *
 * When the atlas has frames WITHOUT polygons (`complete: false`), the
 * full quad corners join the hull so those frames render un-clipped —
 * the envelope degrades toward the quad instead of clipping content.
 *
 * Returns null when the texture has no registered atlas polygons
 * (callers fall back to the synth quad).
