    Linked via "Non-Gaussianity"

    | Spectral Index ($n_s$) | Slow-roll parameters $\epsilon, \eta$ | $0.9649 \pm 0.0042$ | Must be consistent with flatness |
    | Tensor-to-Scalar Ratio ($r$) | $\epsilon$ | $\lesssim 0.036$ (95% CL) | Constrains the steepness of $V(\phi)$ |
    | Non-Gaussianity ($f{NL}$) | Coupling terms in the Lagrangian | $f{NL}^{\text{local}} < 30$ | Distinguishes single-field vs. multi-field models |
