   用 CSS 动画而不是 JS 定时器——标记每 2 分钟整体重绘一次，
   CSS 动画不会因此中断，也不占主线程。

   两个几何注意点（都是踩过的坑）：
   1) 脉冲环动画的是**半径 r**，不是 transform: scale()。圆心在 SVG 里恒为
      (16,16)，改 r 只让圆均匀向外长；transform 依赖 transform-origin，
      在 Leaflet 的 transformed 容器里对 SVG 子元素解析不稳定，会偏心。
   2) 箭头的缩放用显式的 `transform-origin: var(--icon-mid) var(--icon-mid)`，
      不依赖 transform-box: fill-box 推算，缩放中心严格落在 (16,16)。 */
