Mixed-decimals math without explicit scaling

Evidence summary #

CurveStableSwapNG.vy explicitly handles rate_multipliers for decimal normalization of different token types. NG contracts were specifically designed to support mixed-decimal tokens including ERC-4626 vaults with variable decimals. MixBytes audit confirmed fix of rebasing token balance accounting. Decimal normalization is a core design feature of Curve's AMM.

Methodology #

Determine whether shared numerator/denominator arithmetic operates over tokens with different decimals without WAD/RAY normalization or explicit decimal-adjustment.
