Anomalous-Dimension Correction -/ 127 128/-- The anomalous correction to ν on a D-dimensional lattice. 129 130 When the anomalous dimension η ≠ 0, the thermal direction couples to 131 the D field modes at the Q₃ spectral gap (multiplicity D). 132 The correction η/(D + η) is the unique simplest (Padé [0/1]) rational 133 function satisfying: 134 * f(0) = 0 (vanishes at leading order), 135 * f'(0) = 1/D (rate set by the spectral-gap multiplicity). 136 137 On Q₃ with D = `Q3_degree` = 3, the spectral-gap multiplicity equals D, 138 matching the denominator. -/
