Direct kinematic experiments bound the electron-neutrino mass to $m_{\\nu_e} < 0.45$ eV (KATRIN, 90% CL), implying $\\sum m_\\nu \\lesssim 1.3$ eV. Conversely, cosmology within $\\Lambda$CDM is highly constraining: Planck CMB, CMB lensing, and DESI DR2 BAO yield $\\sum m_\\nu < 0.056$ eV (95% CL), in 2-3$\\sigma$ tension with the inverted-ordering floor (0.10 eV). However, this bound relies on $\\Lambda$CDM, while data hint at an evolving dark energy.
