简化加号按钮设计：移除铆钉螺丝槽，强化内凹雕刻效果，导航栏保留倒角凹槽，整体更克制干净

By 18521066629, 2 May, 2026

推理

用户想要简化加号按钮的设计，去掉铆钉/螺丝槽这些细节，只保留加号的刻字（内凹雕刻）样式。同时保留机械接缝的概念——按钮边缘的接缝环线和底部导航栏的倒角凹陷。

让我分析用户的需求：
1. 不需要十字螺丝槽细节（去掉四枚铆钉）
2. 加号改成内陷刻字样式（这个已经有了 text-shadow 的雕刻效果，但可能需要强化）
3. 保留边缘的机械接缝环
4. 保留倒角凹陷设计

我需要简化 btn-plus-float::before 的设计，去掉铆钉相关的 radial-gradient，只保留接缝十字线和边缘环线。同时让加号的刻字效果更加明显。

让我输出更新后的完整HTML。

summary

简化加号按钮：移除四枚铆钉螺丝槽细节，保留圆形边缘内侧机械接缝环线与十字接缝细线，强化加号图标的内凹雕刻刻字效果（深陷暗影+底部微反光模拟金属铭牌刻字），底部导航栏保留倒角凹陷凹槽，整体更加克制干净。
