9/// Resolve exchange of controlled cards between two target players.
10/// Currently delegates to the standard control exchange logic.
11/// Struct form of this effect so it can participate in the
12/// `SpellAbilityEffect` trait hierarchy — mirrors Java's
13/// `ControlExchangeVariantEffect` class extending `SpellAbilityEffect`.
