/**
 * 《声命线》R3 无头试玩仿真测试（26 号文档 playbook 重构版）。
 *
 * 覆盖：
 * - §4.10 首 3 分钟脚本：3 秒内第一次操作、10 秒内第一次成功（ok 回执）；
 * - §4.1 发言权：链间不掉回「轮到你」、tap=跳句、滑动=打断并执行；
 * - §4.2 回执 + 防连点（400ms 内第二下只给 busy）；
 * - §4.3 手势阶梯：up/down/doubletap 未解锁时的处理与首次解释；
 * - §4.4 三档提示：full → short → 提示音；主动重听 = 「再说一遍：」+ 完整句；
 * - §4.5 迷茫接管三级；
 * - §4.12 断点复述；
 * - §6.2 乱点机器人：无声操作 = 0、打断失败 = 0、被动原句重复 = 0、首成功 ≤ 10s；
 * - 资产引用校验（新台词全部落地后零缺失）。
 *
 * 运行：tools/node/bin/node web/storyline/test/playtest.mjs
