 - 导航为下拉菜单，自动高亮当前页；顶部始终显示当前用户头像与用户名。
 - **点导航栏左上角的「🎬 电影日志」即可回到首页**（右键 / Ctrl+点击还能在新标签页打开），不必再展开右侧折叠菜单去找「首页」。
 - 登录页为深色渐变 + 毛玻璃风格。
+- **详情页图片用本页灯箱查看**：海报、票根、观影照片串成一个序列，点任一张即在当前页弹出（不再 `window.open` 到新窗口），**左右箭头翻看并循环**，底部显示「3 / 8」进度与图片说明。
+  可按 **← / →** 翻页、**Esc** 关闭、点画面空白处关闭，手机上还能**左右滑动**切换；弹出时锁定背景滚动，并从相邻位置预取下一张，翻页不白屏。
+  只有一张图时不显示左右箭头；关闭后焦点会回到原来点开的那张图上。
