  "abstract": "Recent anisotropic flow measurements in $^{16}\\rm O{+}^{16}\\rm O$ and $^{20}\\rm Ne{+}^{20}\\rm Ne$ collisions at a center-of-mass energy per nucleon pair of 5.36~TeV provide evidence for nuclear geometry-driven collectivity. In this Letter, we investigate the femtoscopic signatures of nuclear geometry in these light-ion collision systems, using a hybrid simulation framework that couples \\textit{ab initio} nuclear configurations to viscous hydrodynamics and hadronic transport. We show that the $\\rm Ne{+}Ne/O{+}O$ ratio of the freeze-out eccentricity, extracted from azimuthally sensitive femtoscopy, reaches 1.5-1.8 in central collisions for deformed nuclear configurations, compared with about unity for a spherical baseline. This enhancement is significantly larger than that of elliptic flow in the same simulations, and remains stable when pre-equilibrium free streaming is omitted, even though the absolute source radii change considerably. Confronting these predictions with future data will provide new, complementary constraints on nuclear structure and initial-condition modeling.",
