/* ══════════════════════════════════════════════════════════════════════════
 *  以下是 Vue → 静态 HTML 转换时追加的规则
 *  上面 573 行原样保留，一条都没改动。
 * --------------------------------------------------------------------------
 *  用途：复刻第四屏「应用场景」四张卡片的鼠标悬停态。
 *
 *  老写法（PCShortVideo.vue）：
 *    <li @mouseover="svfour_li=1" @mouseleave="svfour_li=0"
 *        :class="{on:svfour_li==1}">
 *  mouseover / mouseleave 成对出现 ⇒ 这是纯粹的悬停态（移出立即复原），
 *  与内容和选中状态无关，所以静态 HTML 里 class 全部写死，
 *  .on 的效果改由下面的 :hover 复刻 —— 视觉等价，页面不需要一行 JS。
 *
 *  特异度与上面 .svfour_kuan ul li.on 系列完全一致，靠「写在后面」生效；
 *  没有改写任何一条 .on 规则，所以 .on 的行为保持原样（若将来要做点击
 *  保持选中态，直接沿用 .on 即可）。
