5/// `SP$ Shuffle` — shuffle one or more players' libraries.
6///
7/// Mirrors Java's `ShuffleEffect.java`.
8/// - `Defined$` selects which player(s) to shuffle (default: You).
9///
10/// # Card script examples
11/// ```text
12/// A:SP$ Shuffle | Defined$ You
13/// A:SP$ Shuffle | Defined$ Each
14/// ```
15/// Struct form of this effect so it can participate in the
16/// `SpellAbilityEffect` trait hierarchy — mirrors Java's
17/// `ShuffleEffect` class extending `SpellAbilityEffect`.
