dsh-chat-tune · 对话区界面设置

DeepSeek Harness Web 插件:在 设置 → 通用设置 里、「外观」正下方增加「对话区界面设置」,调节会话区的字号 / 字体 / 行距 / 段距 / 显示宽度,并可选 滚动时钉住本轮用户消息(类似 Cursor)。不改官方组件——通过覆盖官方 CSS 变量 seam + Client 叠加层生效。

原理

  • 正文字号/字族/行距覆盖官方 seam:--dsw-font-markdown-base / -h1..h4(完整 font 简写)
  • 段落间距改消息列里 p / 列表 / 标题的 margin-block
  • 内容宽度:composerFollow 开启时写在会话根 [data-phase] 上的 --dsh-chat-content-width 与 --dsh-composer-card-max-width;关闭时只改消息列
  • 输入框边缘调宽:composerWidthOnly 开启时裁剪官方 [data-width-handle] 热区,并用 ResizeObserver 同步 [data-composer-seat] 高度到 --dsh-chat-tune-handle-height
  • 钉住本轮用户消息:priority: -1 shadow 官方 user/steering 节点,时间+复制进气泡 DOM;控制器只给当前轮 flow 行打 sticky-head 并 position:sticky(不再用 CSS grid 硬叠官方 IconActions)
  • 代码字体:--ds-font-family-code
  • 选择器挂在 body[data-dsh-chat-tune] 下
  • 偏好存 localStorage(dsh-chat-tune:prefs)

卸载

dsh plugin --profile web remove dsh-chat-tune
