纯红圆形加号按钮简化设计

用户要求：

1. 移除圆形边缘内侧的机械接缝环线（inset shadow ring）
2. 移除十字接缝细线（horizontal + vertical seam lines）
3. 移除外圈装饰环（dashed border）
4. 保留：加号的刻字内凹雕刻样式 + 底部导航栏倒角凹陷凹槽

也就是按钮简化为：纯红色圆形按钮 + 内凹雕刻的加号刻字，底部保留倒角凹槽。按钮外边框（border: 2.5px solid #252525）应该保留，因为这是按钮本身的结构边框。让我想想...

用户说"不保留圆形边缘内侧机械接缝环线与十字接缝细线。外圈的衬线也不要"。这意味着：
- `::before` 里的 inset shadow ring + cross seams 要去掉
- `::after` 里的 dashed border 要去掉
- 保留加号的刻字样式
- 保留底部倒角凹陷

按钮应该保持简洁：红色圆形，深色边框，加号刻字效果。

让我简化按钮样式。

summary

按用户要求大幅简化加号按钮：移除内侧机械接缝环线、十字分割缝线及外圈虚线装饰环，仅保留纯红色圆形按钮主体搭配内凹雕刻刻字加号，底部导航倒角凹陷凹槽保留不变，整体更干净纯粹。
