 - 项目列表采用固定表头表格；剧本、分镜、身份与生产页的目录和详情独立滚动，其他工作区只滚动内容区。
 - 目录、详情、执行记录、折叠操作区、图片历史和 JSON 查看区统一使用 Naive UI `NScrollbar`；外层只负责尺寸与裁切，不再设置原生 `overflow: auto`。内边距与横向排列放在 `content-class` 内容层，避免双滚动条。
 - 身份与形态图库采用限高预览及紧邻其下的横向历史栏；缩略图固定宽度，保留全部候选、辅助视图、失败及进行中记录。点击仅切换预览，不自动切换母版或主图；图片尺寸规则放在非分层组件覆盖样式中，避免被 Naive 按钮默认宽度覆盖。
-- 形态图库卡片采用 `cover` 铺满，点击图片调用 `NImage` 原生预览查看完整原图；“查看图片与记录”仍单独打开历史管理。历史缩略图和其他资源默认保持 `contain` 且不触发原图预览，避免与候选选择混淆。
+- 身份母版、图库大图、历史缩略图、形态／风格／分镜参考图及首帧统一通过 `NImage` 采用 `cover` 铺满。母版与展示图片可点击原生预览查看完整原图；历史缩略图只切换选中记录，再点击大图查看原图，避免与候选选择混淆。“查看图片与记录”仍单独打开历史管理。
 - 拆解页固定精简状态栏与结果标签，设置、预览及恢复操作收进“拆解设置与恢复”面板；人物、场景、道具、分镜和任务明细共用独立结果滚动区，执行记录单独滚动。结果区占满剩余高度，切换标签回到顶部，轮询刷新或开关设置不重置阅读位置；失败与校验提示在面板关闭时仍然可见。
 - 剧集正文按编号连续展示全部已写入剧集；点击目录定位正文，滚动正文同步高亮并保持当前目录项可见。目录分行显示集数和完整标题，执行记录可按需展开。切换角色／世界观等标签不会销毁阅读器或重置位置。
 - 主体身份、分镜设计和镜头生产共用 `DirectoryItem`：编号、完整标题和状态分层展示，桌面目录为 240–280px，窄屏改为可横向滚动的条目。目录标题与筛选固定，只有列表滚动。拆解结果的导出按钮与标签同排右对齐；形态图片筛选按内容区宽度自动排成一行或两列网格。
