"""节点 6.5：产品图生成（product）。
|
||
|
||
在 prompt_build 之后、compose 之前运行（prompt_build → product → compose）：
|
||
热点提示词 → SPU/颜色选品 → basemap 底图 → 纯印花设计稿 → 模特试穿合成图。
|
||
产物写入 output/<country>/product/（底图拷贝 / *_design.png / *_model / *_composite.png / products.json）。
|
||
|
||
模板选择按 SPU.mark 驱动：
|
||
mark==1 → 新三图合成模板 MODEL_WEAR_PROMPT（图1=模特实拍 / 图2=纯印花设计 / 图3=平铺底图）
|
||
mark!=1 → 旧两图合成模板 composite_prompt（底图 + 印花设计 → 平铺服装图）
|
||
|
||
配置（config.yaml product 段）：
|
||
enabled 开关（默认 true）
|
||
db_path SPU/SKU 数据库（默认 db/spu_sku.db，相对路径按运行根解析）
|
||
basemap_dir 底图目录（默认 basemap）
|
||
material_library_dir 模特图库（默认 material_library）
|
||
model_category 模特品类子目录（T-shirt）；为空/无图时取 material_library 第一个有图子目录
|
||
brief_index 用第几个 safe 简报的提示词（0=第一个）
|
||
spu_code / sku_code 指定款号/颜色编码（留空自动选第一个有本地底图的）
|
||
spu_tasks [{"spu": "DG004", "skus": "DG004-BL01,..."}] 多款号批量选品（优先于 spu_code）
|
||
spu_count 款号数量上限（0=不限；取任务清单前 N 个）
|
||
spu_per_color true=每颜色一个 SPU 块；false=单 SPU 下挂所有颜色 SKU 变体
|
||
backend 图像后端：openai(真生图,需 key) / mock(占位) / 留空=跳过生成仅存底图
|
||
|
||
缺底图/模特图时跳过对应步骤并提示，不中断流水线；多款号逐个处理，单个失败不影响其它。
