// test/content/feedback5-swire2-revive-cost.test.js — 琳琅诗怀雅's 破财消灾 (「受到致命伤害时，若费用足够则消耗5点部署费用使生命恢复到
// 70%，每次触发该天赋时消耗的费用翻倍」; 80 % at full potential, the owner's decision of 2026-10-07): the doubled cost restarts at 5 with every deployment — PRTS 备注 「再部署时重置本天赋费用
// 消耗」 (community report of 2026-10-06 「进入联防阶段琳琅诗怀雅所需的复活费用应该重置，正常对局中死亡之后再部署复活费用也应该
// 重置」). A 联防 field is a battle of its own, so it always started at 5; a redeploy used to keep the doubled cost.
