 > **designData 结构遵循 `wechat_wc/docs/design-data-contract-v1.md`（R2/R4 冻结契约）。**
 > 该契约保证 R4 下单后能据此构造 `.wcd` 投递到词云平台。要点：
-> 贴纸图 `src` 必须为 COS 持久 URL（禁止 `wxfile://`/`tmp`）、保留 `wordcloud` 分组、
+> 贴纸图 `src` 在**派单前**必须为 COS 持久 URL；R2 保存/更新清单时允许暂存
-> 保留 `category.mask`；后端该 JSON 白名单须放行 `version/background/wordcloud/rotation/zIndex`。

+> **实现补充（R2，非契约变更）**：服务端 JSON body 传输上限为 **2MB**（`main.ts`，Nest 默认 100KB
+> 会使 1MB 业务限制不可达）。三层边界：≤1MB 正常受理；1MB~2MB 由 design-list service 返回
+> 400「单条设计数据超过 1MB 上限」；>2MB 返回 413「请求体过大」。文件上传（R4 multipart）
+> 不走此限制，沿用各模块独立校验（如底图 ≤10MB）。

+> **实现补充（DIY 修正，非契约变更）**：`stickers[].width/height` 语义为「画布显示像素」
+> （画布坐标空间 = `category.mask` 尺寸，`x/y` 允许超出画布边界，渲染端裁切、WCD 按原值还原），
