- 自定义模式：分析模型输出 delta 唯一改动指令，生图模板 custom_image_prompt.md（{delta} 占位符），不再使用负向提示词；generate_design 按 custom_mode 分支，Pinterest 模式保留原创化指令，两模式互不影响
- 多模态分析 response_format 三级回退（json_schema → json_object → none），兼容 DeepSeek
- 模板导出：details 扩展列（细节1/2/3）、target_audience 扩展列（适用人群1）、固定值风格1=休闲/风格2=运动
- 童装特征库更新 + 标题模板外部化 + 图源映射增强

"""节点 5.5/6：生成印花设计稿 + 导出简报包（compose）。

1. 生成纯印花设计稿：对前 N 个 safe 简报（N=config.compose.design_count，默认 1），

用 image_prompt 调图像后端 generate()（白底、可直接打印），产物存 output/<country>/designs/，

|

2. 导出简报包：design_briefs.json/md、composite_prompts.json/md、report.md。
