 104/-- **LEPTON RUNG DERIVATION**
 105    The charged lepton rungs {2, 13, 19} are derived from the reduced length ℓ
 106    and the generation torsion τ_g.
 107
 108    ℓ = 2 (minimal neutral loop)
 109    τ_g ∈ {0, 11, 17} for generations {1, 2, 3}

 111    r = ℓ + τ_g
 112    Generation 1 (e):   2 + 0 = 2
