/* ==========================================================================
   朝阳薪传 v6.3 · 新增样式
   --------------------------------------------------------------------------
   本文件只放 v6.3 的新组件，原 style.css 不做改动：
     1) 首页 · 朝朝复盘 CTA（呼吸 + 招手动画）
     2) 课后复盘弹窗（7 题 · 语音 · AI 追问 · 识别确认）
     3) 经验库 · 思维树（桌面横向 SVG / 移动端纵向）
   配色与字体全部沿用 style.css 的 CSS 变量，保证与手账 / 水彩风一致。
