/* ============================================================
   collection.css — 书籍 / 网络小说 / 电影 / 番剧 / 物品 页面共用样式
   ------------------------------------------------------------
   由 page_collection.html 按页引入（main.css 先加载，所以这里可以直接用
   第 1 节的令牌）。原本这套样式在五个页面里各存一份内联副本，类名只差
   book-/anime- 之类的前缀；现在统一成 .collection-* 一套。

   状态徽章的配色按语义分三档（tone），而不是按具体状态名：
     active  绿 —— 阅读中 / 观看中 / 在用
     paused  黄 —— 已弃 / 已退役
     warn    红 —— 不再推荐（物品专用：东西会坏会过时）
