V3.3 updates V3.2. The black hole shadow enhancement is now η = √(1+Φ₀) = 1.03033, derived from Φ₀ = 6/5 ζ(3) - 1. The theory passes 7 experimental tests with 0.34σ average deviation. Universal 3.03% prediction for EHT-ng 2028. Zero free parameters. This version supersedes V3.2. All equations tested against EHT, Planck, and Solar System data.
