110
111/-- The 8-tick circle has 8 equally spaced phases at angles kπ/4 for k = 0, 1, ..., 7.
112
113 The electroweak embedding uses 3 of these phases for SU(2) and 1 for U(1).
114 The mixing angle comes from the geometric arrangement.
115
116 Key insight: The "golden cut" of the 8-tick circle gives the mixing angle. -/
