SVG缩放问题：如何让图标占满69px宽高？

你的问题核心在于：SVG的viewBox设为0 0 23 23，但实际logo图形只占据了这个坐标系左上角的一部分（最大x不到19，最大y不到13），当SVG被缩放到69px时，整个23x23的坐标系被放大3倍，空白区域也跟着放大，导致logo只停留在左上角，没填满画布。

下面给你两种直接可用的解决方案：

方案1：强制拉伸填满（允许轻微变形） #

给SVG添加preserveAspectRatio="none"属性，强制图形拉伸到69px的正方形尺寸，直接占满画布：

方案2：保持比例填满（无变形，裁剪边缘） #

先把viewBox调整为logo实际占据的坐标范围0 0 18.5 12.6，再设置preserveAspectRatio="xMidYMid slice"，这样会保持logo比例，裁剪超出正方形的部分，填满画布：

<svg width="69" height="69" viewBox="0 0 18.5 12.6" fill="none" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice">
