// AUTHORED SHIM (not copied). Factory for the no-op BattleCardIconAnimations the headless
// IBattleCardView.BattleCardIconAnimations getter hands back (see _IfaceImpl.g.cs).
//
// BattleCardIconAnimations.Initialize (which seats its private `collection`) is a deferred VFX that
// never runs headless, so a bare `new BattleCardIconAnimations()` leaves `collection` null. The receive
// play path calls BattlePlayerBase.UpdateInPlayBattleCardIconLabel -> HasInductionNumberSkill, which
// iterates `collection.Count()` and NREs on the null. Seed `collection` with an EMPTY
// SkillCollectionBase so the induction-label check resolves to a clean `false` (no cosmetic
// induction-number VFX to play headless). The collection is intentionally empty rather than the played
// card's real skills: the only consumer on the resolve path is this cosmetic icon-label gate, which a
// no-op (empty) collection satisfies correctly. Nothing here touches authoritative game state.
