"summary": "强化整体层次感：①顶部导航栏底部边缘添加1px暖色高光线（模拟光打在上层硬边），同时内容区顶部加inset阴影表现被遮挡；②底部导航栏顶部装饰分隔线改为带高光的双层线（暗线+微暖亮线）；③加号按钮法兰环顶部弧段添加定向高光border；④按钮帽边缘倒角高光微调更锐利，整体层次关系从扁平变得清晰可辨。",

用户想要增强层次感，特别是在上层边缘处添加硬边高光。我需要回顾当前的布局：
1. 顶部导航栏 (nav-top) - 在米白主内容区上方
2. 底部导航栏 (bottom-nav-container) - 在米白主内容区上方
3. 加号按钮 - 在底部导航栏上方
当前顶部导航栏有 box-shadow 投影，底部导航栏也有投影。但用户想要的是边缘处的硬边高光 - 也就是说在上层元素的底部边缘（对于顶栏）和顶部边缘（对于底栏），应该有细线高光来强调层次分割。
具体来说：
- 顶部导航栏的下边缘应该有一条微高光线
- 底部导航栏的上边缘应该有一条微高光线
- 加号按钮的边缘（法兰环等）也应该有高光
让我添加这些细节：
1. 导航栏顶部：底部边缘加一条微暖色高光线（模拟光线打在凸起边缘上）
2. 底部导航栏：顶部边缘加一条微暖色高光线
3. 加号按钮法兰环顶边缘微高光
我会在 nav-top 使用 ::after 伪元素来添加底部高光线，在 bottom-nav-container 的装饰分隔线上方添加高光，以及微调按钮的高光。
另外，内容区（米白色区域）的顶部边缘（在导航栏下方）也应该有一点阴影来表现它被导航栏遮挡的感觉。这可以通过在内容区顶部添加 inset box-shadow 来实现。
让我重新设计这些层次细节。

summary
强化整体层次感：①顶部导航栏底部边缘添加1px暖色高光线（模拟光打在上层硬边），同时内容区顶部加inset阴影表现被遮挡；②底部导航栏顶部装饰分隔线改为带高光的双层线（暗线+微暖亮线）；③加号按钮法兰环顶部弧段添加定向高光border；④按钮帽边缘倒角高光微调更锐利，整体层次关系从扁平变得清晰可辨。
