+ * useSpotlight - 滚动 spotlight / 边缘渐隐
+ *
+ * 行为：
+ *  - opacity 等于「元素在视口中可见的比例」
+ *  - 元素完全在视口内 → 1
+ *  - 元素被滚出一半 → 0.5
+ *  - 元素完全在视口外 → 0
+ *  - 元素比视口高、且完全覆盖视口 → 1
+ *
+ * 关键修复（针对 app-plus）：
+ *  - app-plus 的 <scroll-view> 是原生 UIScrollView，WebView 内容本身不滚动。
+ *    getBoundingClientRect() 永远返回初始 layout 位置（不随原生滚动更新），
+ *    所以基于 rAF/setTimeout + getBoundingClientRect 的方案在 app-plus 上完全无效。
+ *  - 用 uni.createSelectorQuery() 取位置 —— uni-app 官方 API，会桥到原生层，
+ *    在 app-plus / H5 / 小程序上都能拿到当前可视位置。
+ *  - 异步结果用 reqId 防止乱序（连续触发时丢弃旧结果）。
+ *
+ * 用法（square.vue）：
+ *   const { start, stop } = useSpotlight({ getElements })
+ *   onMounted(start); onUnmounted(stop)
+ *   // @scroll 事件也调一次 update()，作为双保险
