SVSimServer/SVSim.BattleEngine/Shim/View/HeadlessAttackSelectControl.cs

// AUTHORED SHIM (not copied) — headless no-op AttackSelectControl for the receive ATTACK path.
//
// The attack conductor dereferences BattlePlayer.BattleView.AttackSelectControl twice on the resolve
// path: InPlayCardReflection.RegisterPairToAttackSelectControl (isPlayer attacks only) calls
// IsCardTranslatable(targetView) + RegisterAttackPair(pair); ActionProcessor.Attack's non-proceeding
// arm calls ResetCardAfterAttack(view). Headless those touch the (UI-only) attack-pair animation state
// — purely cosmetic translate/idle tweening — so a no-op subclass keeps authoritative state intact.
//
// IsCardTranslatable is NOT virtual (it reads cardView.CardInfo.IsClass), so it is left to the BASE
// impl; it resolves correctly headless because the headless BattleCardView's CardInfo is wired to the
// backing card (see Shim/View/ViewUiTouchStubs.cs + Generated/_IfaceImpl.g.cs HEADLESS-FIX). The
// virtual mutating-cosmetic methods are overridden to no-ops here so they never deref the null
// _attackTargetSelectInfo._attackPairsCardIsInvolvedIn animation queue.
