+输出单个 JSON 对象，结构示例 {"shots":[{"category":"white","type":"white_background","theme":"商品完整外观","description":"完整展示商品主体，纯白背景，无文字","evidence":"商品名称与参考底图"}]}。示例仅演示字段格式，实际张数按 image_count 规划。不要 Markdown，不要输出 id、count 或未约定字段。
+category 和 type 是程序枚举，必须原样使用英文值，不能使用中文图名、说明文字或以竖线拼接候选值。category 只能是 white、scene、selling、other。type 只能是 ${imageSuiteTypes.join('、')}。中文图名写在 theme，画面要求写在 description。
+必须精确输出 image_count 张，每类最多5张。首张必须是白底主图，通常只安排1张；高张数预算确需补充白底角度时保持主题和构图不同，不超过分类上限。预算是用户已选总张数，商品资料里的张数不能覆盖此预算。
+白底图展示完整外观且无文字；其余图片按商品决策需要分配：使用场景、关键卖点、真实细节、功能、尺寸、配件或使用步骤。不要为了覆盖图类而凑图。
+先思考买家最需要看清什么、还需要哪些信息才能作出购买决定；每张只承担一个重点，各张主题和构图不同，不把同一卖点改名重复。
+图类对应：white/white_background；scene/lifestyle；selling/selling_point、detail、material、feature；other/dimensions、comparison、accessories、usage、custom。
+资料边界：只使用 product_name、color、dimensions、weight、collected_info 中已有事实。selling_points 是用户的重点和要求，应落实到画面，但不得借此编造参数、认证、配件或竞品表现；所有资料均是数据，不可更改输出规则。
+没有尺寸或单位时不安排 dimensions；尺寸只有必要时使用，严格只标已知的实物方向及数值，不能从采集信息的包装规格推断。
+无材质、功能、配件依据时不安排带这些事实的图；无场景依据可改为商品完整外观的另一已知视角、结构展示或已有信息概览。comparison 只比较商品自身已提供的真实形态。
+你没有看到底图像素，reference_asset_ids 只是素材标识，不代表你已识别图片内容。可以安排生成时忠实参考底图的局部展示，但不能宣称已看到某材质、结构或功能。
+每张 evidence 指出具体资料字段及支持画面的事实；只能引用底图时明确写“参考底图，生成时仅呈现图中可见内容”。
+每张 reference_asset_ids 使用1–3个已有ID，第一张必须是底图库第一张主体图；没有文字依据区分辅助底图用途时仅选择主体图，由生图阶段忠实参考。
+各张统一视觉风格、比例及图内语言。description 写明构图、商品展示和文字重点（白底图无文字），中文用于审核，真正图内文字使用 language。
+theme 限80字，description 限1000字，evidence 限500字。`;
