-  <!-- TripLog 图标：一本翻开的日记本。左页是「家」（出发地），
-       右页是「路线 + 目的地图钉」（旅行），页面底部那道横线是写下的记录。
-       底色用站点主色 accent(#3d6bf5) 的渐变。
-       尺寸取舍：16px 时首页与图钉各只有几像素，所以图形取大、线取粗，
-       只保留「本子 + 一个方正图形 + 一个圆形图形」这层可辨认的形状。 -->
+  <!-- TripLog 图标：一块地图（上），左下角是家（下），右上角是目的地（下），
+       一条弯曲的路线把家连到目的地。
+       地图纹理用「路网 + 带状绿地 + 水域 + 街区小块」叠出来，小尺寸下只求
+       一眼看出「这是一张地图」，不追求地理写实。 -->
