 - 重绘生成资源后，右侧出现新生成结果图层，并自动 fit 原图 + 新图，且重绘面板保持打开。
 - 快速编辑 / 重绘站内 public 示例图、历史 generated 图或 OSS generated 图时，前端先读取成 `data:image/*;base64,...` 再提交，后端不得再收到 `/creation-type-references/*`、`/generated-*` 或 OSS URL 作为 `referenceImageSrcs/sourceImageSrc`。
 - 快速编辑的额外参考图同样必须在前端读取成图片 Data URL 后提交；后端 `referenceImageSrcs` 上限为 9 张，承载 8 张额外参考图加 1 张原图。
-- 素材文件夹可以新建、折叠、重命名和删除；删除普通文件夹后，其素材移动到“项目素材”。
-- 上传按钮和拖拽上传都支持多文件；底部工具栏的上传入口选择文件后直接进入默认素材文件夹并在当前画布视口中心创建画布图层，素材栏文件夹内的上传入口只写入对应素材文件夹、不自动入画布；拖到文件夹或该文件夹内素材时进入目标文件夹；拖到画布时进入默认文件夹并在投放点创建画布图层。上传图片必须在创建占位素材、画布图层和账号级素材记录前先读取原图 Resolution，图层宽高、`originalWidth/originalHeight` 和素材库 `width/height` 都使用图片本身尺寸；仅在无法解析尺寸时才使用上传兜底尺寸。
+- 素材文件夹可以新建、折叠、重命名和删除；删除普通文件夹后，其素材移动到“项目素材”。普通上传默认落入“上传素材”文件夹；素材库缺少该文件夹时，前端在首次普通上传前创建一次并复用，拖到指定文件夹或点击指定文件夹上传时仍进入目标文件夹。

 - 音频 / 视频素材卡和画布媒体图层必须提供稳定的非文字视觉预览：优先使用 `thumbnailSrc` / 视频 `poster`，没有真实首帧或音频封面时使用由媒体类型、素材名和地址派生的确定性视觉底图。视频图层使用原生 `<video controls preload="metadata" playsInline>` 播放，外层图层仍承接选择和拖拽语义；音频图层播放前继续通过 `/api/assets/read-url` 换签。画布素材导出按 `mediaType` 保留真实媒体格式：图片进入 `images/`，音频 / 视频进入 `media/`，文件扩展名从响应 MIME、`objectKey` 或源 URL 推断，不得把音频 / 视频导出成 PNG。
 - `生成角色动作` 的完成结果同样按视频素材处理：图层主 `src` 使用后端返回的 `previewVideoPath`，`mediaType` 固定为 `video`，`assetKind` 固定为 `character-animation`，首个透明帧只写入 `thumbnailSrc` 供 poster 和后续动作源使用。下载和 ZIP 导出必须因此得到 mp4/webm/mov 等真实视频文件，不能回退为首帧 PNG；后端抽帧、绿幕去背和帧素材落盘流程仍完整保留。
