- 新增韩国（KR）适配：countries/pinterest 种子词、K-pop 提示词、UI 国家列表 - 爬虫跨运行持久化已采集 URL（.collected_urls.json），同关键词重复搜索采新图 - 模板导出增强：SPU 商品属性列名前缀剥离匹配、尺码下拉框 INDIRECT 动态引用、 SPU 字段映射（袖长/门襟/胸垫等）、季节/印花图案女装映射、建议售价统一必填、 SKU 分类/数量/单位直接填默认值 - 自定义模式：多模态提示词独立（custom_analyze_*）、生图提示词模板可配置 - Pinterest：空选品守卫、连续空分析保护（max_empty_analyze）、flat_prompt 配置覆盖 - 生图可靠性：开始/完成进度日志、异步任务轮询超时 60s→300s
