怎么填变量：品牌名用两行、每行 3～4 个大写字母最有冲击力；四种口味各配一个底色和一枚小图，底色选彼此区分明显又同样偏哑光的颜色；口味名可以换成中文（每个 4～6 个字）。产品不是巧克力也能用——把"巧克力排"换成"咖啡豆袋""香皂盒""茶叶罐"，版式规则不变。

示例图是米白色背景上的四块巧克力：橙色的一块画着淋焦糖的方块，红色的一块画着带火焰的辣椒，雾蓝色的一块画着可可果，米色的一块画着香草花和豆荚；每块上方都是同样的深棕色大字品牌名和"80% CACAO"，最下面一行是英文口味名。

常见问题：

• 四款版式不一致：强调"四款使用同一模板，只替换底色、插图和最后一行文字"。
• 小图画成彩色插画：写"单色木刻版画风格，线条为深棕色"。
• 字母拼错：品牌名和口味名尽量短，长单词容易错，出图后逐个核对。

适合：口味系列的上新图、包装设计提案、品牌社媒的九宫格素材。
