   智蝶AI · 获客助手 —— v1.3「灵动层」
   ------------------------------------------------------------
   背景：谷总反馈「不够 AI、不够灵动、色系沉暗」。
   本文件只做三件事，其余一律不碰：
     1. 让「AI 正在工作」看得见（思考可视化 + 流式输出光标）
     2. 让平面元素有景深与呼吸（柔光、渐变描边、极光辉光）
     3. 动效全部走 transform/opacity，并尊重 prefers-reduced-motion
   ⚠️ 变量在 style.css 的 :root，改色只改那里。
   ⚠️ 这个文件是叠加层，删掉即可回退到 v1.2 视觉。
