/* toolmsg.css — 工具消息组件（ai/msg/tools/*）共享外观的唯一来源。
 *
 * 这套外壳（头部行、头部图标 hover 互换、状态徽标、折叠体）此前在 10 个组件里
 * 各抄一份——同一份声明 × 10 个不同前缀，改一处要改十处，极易出现
 * 「exec 改了 fs 没改」的语义/视觉漂移。
 *
 * 这里用「前缀选择器列表」一次定义，十个组件共用；各组件 <style> 只留自己
 * 特有的部分（ask/exec 的头部布局、exec 的终端图标、skills 的技能色等）。
 *
 * 前缀对照：gt=通用 tool、mem=记忆、fs=文件、ex=执行、ask=问答、tk=任务、
 *            dl=委托、cp=压缩、sk=技能、ws=联网搜索。
 *
 * 优先级说明：本文件是全局基线（选择器特异性 0,1,0）；组件内 <style> 经 vhtml
 * 作用域化后特异性更高（0,2,0+），组件特例覆盖本文件，同名同属性时以组件内为准。
