 * iOS 包 H5 迁移 — 本地模拟器(假数据 + 场景预设)
 * ============================================================
 * 用途:后端 /api/mig/* 未就绪时,在本地/测试环境完整走通客户端全流程。
 * 开关:isDebugEnv()(localhost / 192.* / *.usgamewin.com)下,URL 带 ?migsim=1 开启、
 *       ?migsim=0 关闭;状态明文存 localStorage(MIG_SIM / MIG_SIM_STATE),生产域名永远不生效。
 * 原则:客户端逻辑全部真实,仅 service.js 的网络层被替换成本文件的假实现。
