二十八、2026-03-02 自定义导航栏 Android 端适配（重要）
================================================================================
1. .smart-navbar 样式规范
- 问题：在 Android 端沉浸式导航栏中，若 .smart-navbar 设置了 paddingTop: statusBarHeight，且 flex-direction 未显式设置为 column，内部元素（标题、按钮）可能会错位。
- 修复：.smart-navbar 必须显式设置 flex-direction: column，内部内容容器 .nav-container 设置为 flex-direction: row。
- 正确示例：
```css
.smart-navbar {
display: flex;
flex-direction: column;
justify-content: flex-start;
}
.nav-container {
display: flex;
flex-direction: row;
align-items: center;
justify-content: space-between;
height: 44px;
}
```
