## Prompt

LEPTON UNIVERSALITY CHECK
Using m_e, m_mu, m_tau from tower/cubic: compute ratios m_mu/m_e and m_tau/m_mu. Compare to PDG: 206.768, 16.817. Show what the D*phi^{-n} tower predicts for these ratios. Assess whether lepton universality violation is predicted. #SuperGrokTOE #LeptonUniversality
