 ## 生成规范参考图
 
-- `生成规范 -> 角色规范`、`图标规范`、`图标规范`、`自定义规范` 的设定面板都支持上传 1 张参考图，并统一放在面板首行参考图区域。
+- `生成规范 -> 角色规范`、`自定义规范` 的设定面板支持上传多张参考图，最多 5 张；`图标规范` 保持单张规范参考图。所有参考图统一放在面板首行参考图区域，并可逐张删除。
 - 参考图入口只展示字段标题、缩略图或上传图标、文件名，不把参考规则说明铺在 UI 上。
-- 提交生成规范时，若存在参考图，前端必须把参考图作为 `referenceImageSrcs[0]` 提交到 `/api/editor/images/generations`，并在生图提示词开头自动追加“参考图生成规范”语义：要求模型参考图 1 的构图、风格、材质、色彩、形状语言和视觉层级生成规范图，但不要复制参考图中的文字、水印或无关背景。
+- 提交生成规范时，若存在参考图，前端必须按用户当前顺序把全部参考图提交到 `/api/editor/images/generations` 的 `referenceImageSrcs`，并在生图提示词开头自动追加“参考图生成规范”语义：要求模型参考图的构图、风格、材质、色彩、形状语言和视觉层级生成规范图，但不要复制参考图中的文字、水印或无关背景。
 - 生成结果的信息快照必须记录该参考图，标题为 `参考图`，便于后续在图片信息面板回看生成输入。
