 *
 * 两套布局：PC（≥961px）+ H5（<961px），由 landing.js 在 detectDevice 后给
 * <main.landing> 加 data-layout="pc"/"h5" + data-os="ios"/"android"。
 * 热区位置全部精确测自 Figma node 637:260 的 absoluteBoundingBox（见
 * doc 落地页/landing板块实施方案.md §7）。
 *
 *  - PC 背景：3840×2160 (Figma node 637:26 @2x，原 1920×1080 设计稿)
 *  - H5 iOS：750×1270 (node 637:100 裁掉 iPhone 状态栏 88px + Safari 栏 266px)
 *  - H5 Android：750×1536 (node 637:159 仅裁状态栏 88px，无 Safari 栏)
 *
 * iOS / Android 两张 H5 背景图尺寸不同 → 热区百分比按各自图分别算，通过
 * .landing[data-os="ios|android"] 选择器切换。url 加 ?debug=1 可看红框对齐。
