 226/-! ## Part 5: Gauge Rank Correspondence -/
 227
 228/-- The **gauge rank** of a layer: the number of independent generators.
 229
 230    For a Lie group of rank r:
 231    - SU(n) has rank n - 1, acts on ℂⁿ (fundamental rep dimension n)
 232    - U(1) has rank 1
 233
 234    The cube layers provide the FUNDAMENTAL REPRESENTATION DIMENSIONS:
 235    - S₃ acts on 3 axes → fundamental rep dimension 3 → SU(3)
 236    - (ℤ/2ℤ)² acts on 2-element subsets → fundamental rep dimension 2 → SU(2)
 237    - ℤ/2ℤ acts on parity → fundamental rep dimension 1 → U(1) -/
