   FinLearn 微交互与板块层次层
   --------------------------------------------------------------------------
   解决的问题（用户反馈）："鼠标移到哪里、点击哪里，要有对应的动态感；
   板块之间也要有板块感"。

   审计数据：全站 :hover 仅 97 处、:active 仅 3 处、可交互元素大量没有过渡，
   因此鼠标经过、按下时几乎没有任何反馈。

   本层做两件事：
     一、交互反馈（fidelity）—— 每一个可交互元素都有 hover / active / focus 三态
     二、板块层次（hierarchy）—— 用底色分层、分区带、标题装饰、分隔线建立区块感

   实现约束（对齐 ui-ux-pro-max 与 scroll-craft 的规则）：
     · 只动 transform / opacity / background-color / border-color / box-shadow
     · 统一使用 --ease-* 与 --dur-* 令牌，禁止随机时长
     · 全部在 prefers-reduced-motion 下降级
     · focus-visible 一律保留可见焦点环（可访问性硬要求）
