"summary": "将加号按钮从凸面改为扁平嵌入式机械按钮：移除径向渐变凸面高光改为均匀哑光平面，按钮帽与法兰环处于近乎同一平面高度，inset阴影改为极浅微斜面暗示倒角，机械缝隙收窄至1.5px，法兰外缘过渡更柔和，加号刻字保留V形槽倒角，整体呈现面板齐平的精密工业按钮质感。",

推理
用户希望按钮更加扁平化。回顾当前设计，按钮是凸起的（有径向渐变模拟凸面），用户希望它更扁平。我需要：
1. 移除凸面径向渐变，改为更平的表面处理
2. 减少凸起的立体感
3. 保持机械缝隙和法兰结构
4. 保留刻字加号
5. 让它更像一个嵌入面板的扁平机械按钮
让我重新设计这个按钮：扁平表面、微妙的内凹刻字、机械缝隙和法兰环保留但更克制。

summary
将加号按钮从凸面改为扁平嵌入式机械按钮：移除径向渐变凸面高光改为均匀哑光平面，按钮帽与法兰环处于近乎同一平面高度，inset阴影改为极浅微斜面暗示倒角，机械缝隙收窄至1.5px，法兰外缘过渡更柔和，加号刻字保留V形槽倒角，整体呈现面板齐平的精密工业按钮质感。
