   绒华录 · AI创作（对话）扩展样式表
   --------------------------------------------------------------------------
   说明：
   1. 本文件只做「新增」，不覆盖、不修改 工坊2style.css 里的任何既有规则；
   2. 页面默认（空态）视觉与改造前完全一致，只有进入对话后才出现新元素；
   3. 设计令牌全部沿用既有页面：
        朱砂红  #970002      腮红粉  #EFBFB5      纸感米色 #F9EEE4
        描边灰  #CECECE      正文灰  rgba(0,0,0,.6)
      字体沿用：标题 'source-han-serif sc vf medium', serif / 正文 "Microsoft Yahei", sans-serif
   4. 尺寸严格锁定 375 × 812，不产生任何滚动或位移。
