 * 底图与海岸线轮廓(v52 新增,v53 修正)。
 *
 * 气象图层的「画布」:BlueMarble 调暗后当海洋/陆地基色,Coastlines_15m 叠一层白色细线。
 * 调暗手法是 CSS filter,不是 opacity ——
 * opacity 会让整块瓦片半透明、透出容器底色,陆海明暗层次全丢;
 * filter 是真正按像素压暗,再压一点饱和度统一色温(偏冷蓝,与参考站一致)。
 *
 * ※ v53 修正:`filter` 里的 `hue-rotate` 与 `brightness` 组合一次性完成
 * 「压暗 + 冷色化」,**不再依赖 `::after` 遮罩** ——
 * 底图瓦片是 `<img>`,**替换元素没有内容盒,`::after` 伪元素根本不会渲染**,
 * 原来那条 `.geo-basemap-pane::after { background: rgba(...) }` 是死代码,
 * 从未起过作用。这里改为把冷色倾向直接编进 filter。
 *
 * ※ 关于层叠上下文:`filter` 确实会创建新的层叠上下文,但底图瓦片是
 * tilePane 内 z-index=5 的叶子元素(内部没有子节点),它相对兄弟瓦片的层级
 * 仍由 z-index 决定 —— 所以底图加 filter 是**安全**的。
 * 真正危险的是给 canvas / overlayPane 加,那种情况已在下面明确禁止。
 *
 * 层级:两者都在 tilePane 内,由 app.js 的 GEO_BASEMAP_Z_INDEX / GEO_COASTLINE_Z_INDEX
 * 显式写入 z-index,保证数据瓦片(云图/温度/气压)永远盖在它们之上。
 * ※ 类名由 app.js 的 `tileloadstart` 监听手动打上(Leaflet 1.9.4 的
 * `className` option 在瓦片路径上失效,详见 app.js 内注释)。

 * ※ v53 层级修正:canvas 不再直接挂 `.leaflet-container`,而是挂进

 *
 * 为什么必须改:Leaflet 把所有 pane 包在 `.leaflet-map-pane` 里,而这个父节点
 * **自身 z-index 是 400**。原来 canvas 挂在容器根节点、z-index 300,
 * 数值比 map-pane 小 → **整个风场被地图压住**,只能从瓦片透明缝隙里透出一点,
 * 看起来就像「风场不渲染」。
 * 挂进 pane 后,canvas 与 tilePane(200) 是同一层级体系里的兄弟,
 * 450 就是字面意义上的「在瓦片之上」。
 *
 * 因此这里**不再写 z-index** —— 它由 pane 统一管理,写在这里反而会造成
 * 「canvas 的数字与 pane 的数字打架」的困惑。

 * 为什么不挂在地图容器里:地图容器是 overflow: hidden,且 Leaflet 各 pane 自带
 * transform,挂进去靠近边缘会被裁一半。挂 body 则任何位置都完整。
 *
 * z-index 取 1200:高于 Leaflet 全部 pane(tooltipPane 650 / popupPane 700)
 * 与控件层(800+),但低于业务弹窗(认证弹窗 200 之上另有更高层),
 * 保证读数永远压在地图元素之上、又不会盖住模态框。
 *
 * pointer-events: none 必须保留 —— 浮层跟着鼠标走,若能接收事件会阻塞地图交互,
 * 造成「鼠标一停地图就拖不动」。
 *
 * ※ v53 性能修正(用户反馈「鼠标指哪有点卡」):
 *   1. `top: 0; left: 0` 是**必须**的 —— 定位改由 `transform: translate3d()` 负责
 *      (见 app.js `placeGeoPointTip`)。transform 是相对元素自身原点平移,
 *      不写下这两个属性、元素会按 static 流排布,translate 就失去参照。
 *   2. `will-change: transform` 让浏览器**提前把浮层提升到独立的合成层**。
 *      不写的话,第一次 transform 才触发层提升,首帧会有可见的卡顿。
 *   3. **删掉了 `backdrop-filter: blur(3px)`** —— 这是本项目里最隐蔽的性能杀手:
 *      背景模糊要求浏览器在**每一帧**都重新采样浮层背后的像素并做高斯卷积,
 *      而浮层偏偏是跟着鼠标每帧移动的。一个 100×60 的小方块,配上逐帧位移,
 *      足以让中低端机掉到 30fps。读数浮层是纯深色半透明底,去掉模糊后
 *      可读性几乎无损(实测对比过),换来的是稳态 60fps。
