怎麼填變量：品牌名用兩行、每行 3～4 個大寫字母最有衝擊力；四種口味各配一個底色和一枚小圖，底色選彼此區分明顯又同樣偏啞光的顏色；口味名可以換成中文（每個 4～6 個字）。產品不是巧克力也能用——把"巧克力排"換成"咖啡豆袋""香皂盒""茶葉罐"，版式規則不變。

示例圖是米白色背景上的四塊巧克力：橙色的一塊畫着淋焦糖的方塊，紅色的一塊畫着帶火焰的辣椒，霧藍色的一塊畫着可可果，米色的一塊畫着香草花和豆莢；每塊上方都是同樣的深棕色大字品牌名和"80% CACAO"，最下面一行是英文口味名。

常見問題：

• 四款版式不一致：強調"四款使用同一模板，只替換底色、插圖和最後一行文字"。
• 小圖畫成彩色插畫：寫"單色木刻版畫風格，線條為深棕色"。
• 字母拼錯：品牌名和口味名盡量短，長單詞容易錯，出圖後逐個核對。

適合：口味系列的上新圖、包裝設計提案、品牌社媒的九宮格素材。
