 157/-! ## Comparison with Axion -/
 158
 159/-- RS vs Axion solution:
 160
 161    **Axion**:
 162    - Requires new particle (not yet detected)
 163    - Continuous relaxation to θ = 0
 164    - Makes dark matter prediction
 165
 166    **RS 8-tick**:
 167    - Uses existing structure
 168    - Discrete quantization of θ
 169    - θ = 0 by J-cost selection
 170
 171    Both predict θ ≈ 0, but mechanisms differ. -/
