 - 作品详情头图的「订阅」改回普通主按钮（静态高光在剧照上看得清），去掉实心按钮例外 `pill-solid`；发现页海报上的评分与状态角标改成烟色小玻璃。
 - 触屏判断改为通用方案（`<html data-input>`、`touch:` 变体、`useTouchInput()`）：车机等把触屏报告成鼠标的设备也按触屏处理，悬停效果只给真鼠标。
 
+### 修复
+- 站点快照加 5 分钟总截止时间：请求在过人机验证、浏览器代抓或限流排队时卡住，快照到点记为失败，后台任务不会一直停在运行中（之前 OurBits 的一次定时快照卡了 10 小时）。
+- 定时任务在认领或收尾写库时出错（如关停时连接已断）不再成为未处理的错误，改为记一条日志。
+
