/* ==========================================================================
   聊天记录取证导出 · 独立设计「证据卷宗台」
   --------------------------------------------------------------------------
   设计概念：把取证做成整理卷宗——左边是案件与步骤，右边是「证据三性」
   仪表与存证等级，每一步都像在装订一份可提交的材料。
   配色：藏青 + 暗金 + 证物红，严肃但不压抑。
   所有规则限定在 .tsk.cea 作用域内。
