// Task 10 互动化 Playwright(真实后端 + 真实 WS/点赞/浏览管线):
// · 大图真实点赞 ×3 → 计数权威 3 → 刷新持久;
// · 气泡自身过滤(双真实浏览器上下文:他赞出气泡、己赞不出);
// · WS 不可达(__viewerWsUrl 死端口注入;setOffline 不切断已建 WS,见用例注)
// → 三败降级轮询校准计数 → 翻回真实 URL 重连 open;
// · 照片下线 WS 推送 → 序列即时移除 + 大图回退邻居(deleteSeededPhoto+flushSync);
// · 排序切换(最新/热门):API 直推 B 点赞 → 热门置顶;大图开时 chips 禁用;
// · 浏览上报:全新上下文计数 +1,刷新不重复,第二上下文再 +1;
// · 减少动画:他赞无气泡、计数照常校准。
// e2e 注入点:__viewerRealtimePollMs / __viewerWsRetryBaseMs / __viewerBubbleMs /
// __viewerWsUrl(沿用 __viewerPollMs 约定);连接态锚 .activity[data-connection]。
