3218485270 b7f429db89 模板导出增强 + 模特性别分组 + 三合一提示词精简
1) 模板导出:识别「基码表-胸围」填 sku.bust(多个胸围列都填);申报价格模糊匹配多列统一按加价后价格填写;详情图文不再拼接 img_url_2;SPU 款式来源统一填「现货款」;商品产地国家简称映射(沙特→沙特阿拉伯)
2) 模特性别分组:model_features 按男女分组,按模板类目含男/女固定取对应性别模特(含 Pinterest 模式 pipeline)
3) 三合一提示词:去掉 DESIGN CONTENT 四要素描述(设计已由设计稿提供)
4) 生图尺寸:全部改为读 config 不再硬编码(设计图 compose.design_size / 合成图 compose.size / 种草图 seed_shot.size)

"""Pinterest 参考模式节点 3/3:从图池取图 → 多并发 LLM 分析 → 原创设计简报(pinterest_analyze)。
图池机制:
- 从持久化图池(image_pool.json)取「未消费」图片(md5 不在 used_images.json)。
- 大图先压缩(内存占用过大 → 缩放/重编码)再送 LLM。
- 多并发分析(每批 analyze_per_term 张,并发 analyze_concurrency 线程)。
- 每张被分析的图片 md5 一律拉黑(used_images.json)——合适→产出简报→生成设计(设计 md5 全局拉黑见 compose);
不合适→图片 md5 已拉黑→下一轮自动取下一张,不重复分析。
- 图池无未消费图片时返回空,由路由触发新一轮搜索。
兜底链:LLM 多模态 → 纯文本降级(后端内部)→ mock 规则简报 → 空列表(下游跳过)。
带 with_fallback:任何异常都不中断。
