/* 与活动页的跨文档过渡配对 —— 对端在 activity-demo/brand.css。
       两页都声明 @view-transition 后，整页跳转不再是一帧硬切：
       同名元素保持位置，其余内容交叉淡入，因此「个人中心 → 官网首页」这一跳
       是渐变而不是场景硬换。这里只声明在本页，所以首页 ↔ 活动页会过渡，
       官网其余页面之间维持原来的即时跳转。Firefox 稳定版还不支持
       跨文档过渡，会自动降级为普通跳转，无副作用。 */

       ease-out 类曲线在时间过 10% 时就走了 40%，放进交叉淡入里等于把时长吃掉。
       交叉淡入本质是「溶解」，均匀才平缓，所以这里用 linear，时长 .4s：
       实测进度严格落在 25% → 0.25、50% → 0.50、75% → 0.75。
