/**
 * 原值：这份文件断言回答的第二层是一个默认收起的 `<details class="answer-detail">`
 *       「完整分析」控件（`chat-answer-detail.tsx`），并锁住它的 caption、流式期
 *       不渲染子节点、以及它与 technique-audit 是两套样式。
 * 新值：控件与组件文件一并删除，报告层直接渲染进正文 `.answer-report-body`。
 * 原因：产品在真机走查后拍板——首个 H2 之后的全部内容（也就是带推理的那一半）
 *       默认不可见，用户「输出根本看不到」。回答本身就是产品，不该藏在一次点击后面。
 *       技法审计表保留它自己的折叠：那是给人核对的证据，不是回复正文。
 *
 * 下面保留的断言是原文件里与折叠无关、仍然成立的那些（记忆化、复制取原文、
 * onboarding 走同一渲染链），并新增两条锁住「不得再把回答折起来」。
