-- 风格：2D 扁平化教育动画，简洁现代的信息图风格
-- 配色：深蓝色渐变背景（#1a1a3e → #2d2b55），白色/浅蓝文字，粉色/青色强调色
-- 字体：无衬线粗体标题 + 常规正文，文字全部使用英文，文字居中对齐
-- 布局：核心信息居中展示，四周留白，底部可放置页码或进度指示
-- 严禁：任何中文字符出现在画面上！所有文字必须翻译为英文
-- 严禁：任何真人、卡通人物、人物剪影、手指指引等拟人化元素
-- 元素：仅使用几何图形、箭头、色块、图标、表格、下划线、高亮标记等抽象视觉元素

-**分镜 visual 字段编写规范：**
-1. 每个分镜的 visual 必须以"深蓝色渐变背景"开头，确保背景统一
-2. 描述具体的视觉元素和动画效果，避免模糊描述
-3. 相邻分镜之间应有视觉延续感（如颜色过渡、元素呼应）
-4. 每个分镜聚焦一个核心知识点，视觉元素不要过于复杂
-
-**请根据试题的复杂度自行决定分镜数量（建议 3~8 个，简单题 3~4 个，复杂题 5~8 个），确保讲解充分且每个分镜信息量适中。**`;
