/* ==========================================================================
   滚动渐入（Scroll Reveal）
   --------------------------------------------------------------------------
   效果：元素进入视口后淡入 + 上移复位，同组内逐张错峰，只播一次。
   三段机制：
   1) html.lj-rv-on 由 <head> 内联脚本在首次绘制前加上，配合下面的
      「静态选择器清单」先把目标设为不可见 —— 杜绝"先显示后隐藏"的闪烁。
   2) 用 animation 而不是 transition 驱动，避免覆盖卡片自带的 hover 过渡。
   3) 位移用独立的 translate / scale 属性，不碰 transform，卡片悬浮上移照常。

   ★ 目标来源改为「结构约定」，新增页面无需再改清单：
      ① main > *              每个页面的顶级区块（任何新页面放进 <main> 即可）
      ② [data-rv-group] > *   需要逐张错峰的容器（在容器上加这个属性）
      ③ 历史清单              站点早期页面用到的分组 / 独立区块，保持向后兼容
   ⚠ ①② 是结构性选择器，assets/js/main.js 用同一套字符串注册，
     两侧天然同步；③ 若再新增模块，请优先加 data-rv-group 而不是往清单里塞类名。
