109/-- The mass hierarchy between generations scales as φ.

113/-- Approximate mass ratios in the Standard Model:
114 - top/charm ≈ 130 ≈ φ^10
115 - charm/up ≈ 500 ≈ φ^13
116 - tau/muon ≈ 17 ≈ φ^6
117 - muon/electron ≈ 207 ≈ φ^11

123/-- **THEOREM (Hierarchy from φ-ladder)**: Each generation sits on a different
124 rung of the φ-ladder, giving exponential mass ratios. -/

128/-! ## Why Not 2 or 4 Generations? -/
129
130/-- Could we have 2 generations? No - D=3 requires 3 dimensions.
131 Could we have 4? No - 8 = 2³ gives exactly 3 bits.
132
133 **Proved**: 8 = 2^3 and the number of bits in a byte is 3 (log₂ 8 = 3). -/

135 -- 8-tick cycle has exactly 3 bits, corresponding to 3 dimensions

138/-- **THEOREM (No Fourth Generation)**: Electroweak precision tests and
139 Higgs production rule out a 4th generation with SM-like couplings.
140 RS explains WHY: there's no "room" in the 8-tick structure for a 4th. -/
