// test/sim/bossfield.browser.test.js — the Final Assault / Hidden Core fields in the BROWSER sim (DESIGN §14: the
// clients simulate the boss fields; the server re-simulates them for SP_VERIFY and takeovers). A real bot co-op match
// (终极, seed 14 since 0.1.1 — the bots and the rules of 0.1.1 play seed 12 to boards without a 麻痹 or a 剑 / 锤
// transfer on every field; seed 14's pair fields carry 奥术, 催泪瓦斯 and 限伤-sized hits) is played to the Hidden Core
// with every active bond at the official 999 layers (DESIGN §20.12); its four captured boss specs (R14 假想敌：胄 boss_1, R15 隐秘核心 boss_8) run to
// the end in Node and in headless Chrome through the client's own loader (public/js/battle/runner.js loadBrowserSim)
// with the field's LocalBossPool, and must give the same result digest, the same pool and the same fx per kind.
// The fields exercise the playtest-6b sim paths: 直接乘算 bonus sums (§20.10), one 奥术 instance per target
// (applyStrongest), the drone 2 % links and the 剑 / 锤 / shell kit (§20.13), and 限伤 cancels (fx 'hitCap', §20.12).
//
// Opt-in (starts Chrome): SIM_E2E=1 node --test test/sim/bossfield.browser.test.js   (or RENDER_E2E=1)
// Run browser test files one at a time. Chrome path: $CHROME_PATH or the macOS default.
