 - 按最新反馈移除整行榜单与热度胶囊，信息顺序收敛为标题、剧名、标签、简介、观看全集。
 - 剧名 19/w600，箭头 20 白色并紧邻剧名；标签行改为 13/w600 亮灰内联布局。
 - 简介「展开/收起」沿用现有三语文案；进度条热区恢复 24 并接入拖动自动清屏与预览卡片。
-- 拖动期间隐藏操作栏、文字及根底栏，顶部导航常驻；松手后持续清屏直到点击画面。
+- 拖动仅控制视频浮层内容，顶部导航与根底栏保持常驻。
-- 进度条固定中心并动画到 6 高，时间气泡限制在左右 12；松手恢复拖动前浮层状态。
+- 进度条固定中心并动画到 6 高，时间气泡限制在左右 12；end/cancel/pointer 兜底均恢复拖动前状态。
