Quench dynamics in three-level dipole-interacting Rydberg arrays produce scalable spin-nematic squeezing with ξ² ∝ N^{-2/3} (all-to-all symmetric) or N^{-0.7} (antisymmetric), yielding F_Q ∝ N².
A quartic extension of the twisting-and-turning Hamiltonian generates new unstable fixed points that accelerate short-time amplification of quantum fluctuations, yielding enhanced sensitivity within accessible coherence times.
