// test/content/feedback7-champagne-stealth.test.js — 琳琅诗怀雅's 香槟炸弹 does not go off on a 隐匿 enemy that is neither
// revealed nor blocked (community report: 「香槟炸到没有破隐的隐匿敌人了」). PRTS 作战机制 §隐匿: "隐匿效果使得获得该效果的单位无法被
// 任何敌方的能力索敌选中" — the bomb's pages carry no 无视隐匿 note, and the other contact traps (多萝西's 共振装置, 望's 棋子)
// select their enemies so too. A revealed (反隐) or blocked one, and every visible ground enemy, still set it off.
// Run: node --test test/content/feedback7-champagne-stealth.test.js
