 109/-- Key insight: In RS, the cosmological constant arises from
 110    the DIFFERENCE between positive and negative J-cost contributions.
 111
 112    1. Positive contributions: Each field mode adds ~E_P
 113    2. Negative contributions: φ-structure provides cancellation
 114    3. Residual: The tiny observed Λ
 115
 116    Λ_eff = Λ_bare - Λ_φ-cancel + Λ_residual
 117
 118    The residual is ~10⁻¹²² of the bare value! -/
