Importance: Important supporting result: establishes the flat benchmark where curvature vanishes. Understanding rho=0 is essential context for all curvature-dependent results.
Novelty: The CD limit of CES is classical (Arrow et al. 1961). The contribution is showing it as the watershed where all nine roles deactivate simultaneously, a new framing of a known result.
Quality: Excellent structure with clear L'Hopital derivation, comprehensive list of CD properties, and well-motivated explanation of why economists default to CD.
