// Community report of 2026-10-06 (items 9 / 37) 「卡西米尔和艾芒加德策略似乎有BUG：像砾和瑕光这种死亡和部署的叠层效果，如果有
// 艾芒加德的3次复活似乎是无法触发…只有最后一次真的死了没站起来才叠层了」: 埃芒加德's 命结之秘 (and M3茧甲) revived in place — a
// `fatal` saver — so no 被击倒时 and no 部署时 effect fired. PRTS (卫戍协议：盟约 下半/PRTS盟约记录, 埃芒加德 and M3茧甲 备注):
// "“复活”的实现方式为：受益者因移动之外的原因退场时下次部署的再部署时间和费用归零" — the knock-out stands and the operator
// redeploys at once, free: items/battle.js reviveNow, a `death` hook.
