  "abstract": "We theoretically demonstrate that the molecular orientation angle $θ$ provides a structurally intrinsic, continuously tunable control parameter for engineering optical Schrödinger cat states via high-harmonic generation (HHG) in H$_2^+$. Coupling time-dependent Schrödinger equation simulations to the fully quantized HHG framework, we evaluate the Wigner functions of the post-selected harmonic-mode states under two complementary conditioning strategies. Conditioning on resonance-enhanced low-order harmonics exploits the complementary dipole selection rules of the $1σ_g\\to1σ_u$ and $1σ_g\\to1π_u$ transitions, driving a kitten-cat crossover whose direction is opposite in the two channels as $θ$ is varied. Conditioning on plateau harmonics instead exploits two-center destructive interference, producing a reentrant cat$\\to$kitten$\\to$cat transition controlled by the order-dependent interference angle $θ^*(q)$. In both cases the crossover is decoupled from the laser intensity, focal geometry, and molecular density, offering a degree of control with no counterpart in atomic targets.",
