用户要求去掉法兰环样式。回顾一下当前加号按钮的设计，有一个机械间隙（gap-color）和法兰环（#3c3835），以及法兰外缘倒角。用户希望去掉所有这些法兰相关的样式，让按钮更简洁。
我需要：
1. 移除法兰环相关样式（0 0 0 3.2px #3c3835 及其外缘倒角）
2. 保留按钮本身的红色帽体+同心圆纹理+内凹刻字
3. 保留机械间隙（gap-color）作为按钮与面板的分界
4. 保留面板倒角凹陷
5. 移除 ::before 伪元素的法兰顶部弧光
让我设计一个更简洁的按钮：仅保留红色圆形按钮帽体（带同心圆纹理），周围有一圈暗色间隙，没有法兰环。按钮直接嵌入面板的倒角凹陷中。
另外，::before 伪元素是法兰环顶部弧光，这个也需要移除。如果不需要伪元素可以删除或者改为其他用途。目前看 ::before 是法兰弧光，去掉后就完全不需要伪元素了。
调整 box-shadow：
- 保留按钮帽边缘倒角 (inset)
- 保留机械间隙 (0 0 0 1.8px var(--gap-color))
- 移除法兰环 (0 0 0 3.2px #3c3835)
- 移除法兰外缘倒角 (后面两层)
- 保留投影
这样按钮就是一个简单的红色圆形嵌入面板中，周围只有一圈暗色间隙。

summary
移除全部法兰环样式：删除法兰环box-shadow层、法兰外缘倒角层、::before弧光伪元素，仅保留红色按钮帽体（同心圆纹理+刻字）与一圈暗色机械间隙嵌入面板倒角凹陷中，按钮更简洁干净。
