The fine-structure constant (1/137.036) is a geometric cross-ratio, invariant under coordinate transformations.
New paper classifies all 26 Standard Model dimensionless constants into 3 types and scans 600 scale combos. Result: Type I (couplings) are invariants; Type II (mass ratios) resist cross-ratio expression.
