inspirepan Flat Illustration
生成单张有层次的扁平设计插画：整体仍是干净几何、大色块和纯背景，但主体要像分层 2D 角色一样有厚度、接触阴影、分面光影和右上方光源。适合把人物、动物、植物、角色、小物件做成轻盈、可爱的 icon-like 插画。
适用场景
- 用户明确说“扁平插画 / flat illustration / layered vector illustration / Live2D-like”。
- 把一个主体画成干净、几何化、有光影层次的单张插画。
- 适合头像候选、文章配图、贴纸感小插画、产品空状态插画、简单角色展示。
不适用：真实摄影、复杂场景、漫画分镜、信息图、UI 界面、产品广告、电影感画面、品牌 logo 设计、需要大量可读文字的海报。

Prompt 模板
调用 GenImage 时，按下面模板拼出完整 prompt，并把比例放在工具参数 ratio 里。
A layered 2.5D flat design illustration of a [subject], presented in a [front-facing / side-facing / three-quarter], minimalistic style. Set against a plain [background color], the artwork uses a soft palette of [color1], [color2], and [optional accent color]. Build the subject from overlapping rounded geometric shapes with visible depth: separated parts, contact shadows, simple cel-shaded planes, and subtle edge highlights. The light source comes from slightly above and to the right, creating brighter upper-right edges and muted lower-left shadow shapes. Clean balanced spacing, simple geometric charm, no text, no logo, no watermark.

示例
A layered 2.5D flat design illustration of a cat sitting calmly, presented in a front-facing, minimalistic style. Set against a plain warm beige background, the artwork uses a soft palette of cream, warm gray, and charcoal gray. Build the cat from overlapping rounded geometric shapes with visible depth: separated ears, head, cheeks, chest, paws, and tail; contact shadows; simple cel-shaded planes; and subtle edge highlights. The light source comes from slightly above and to the right, creating brighter upper-right edges and muted lower-left shadow shapes. Clean balanced spacing, simple geometric charm, no text, no logo, no watermark.
A layered 2.5D flat design illustration of a cactus in a pot, presented in a front-facing, minimalistic style. Set against a plain sand yellow background, the artwork uses a soft palette of sage green, deep green, and terracotta. Build the cactus pads and pot from overlapping rounded geometric shapes with visible depth: contact shadows, simple cel-shaded planes, a clear pot rim and side planes, and subtle edge highlights. The light source comes from slightly above and to the right, creating brighter upper-right edges and muted lower-left shadow shapes. Clean balanced spacing, simple geometric charm, no text, no logo, no watermark.
A layered 2.5D flat design illustration of a cheerful jumping game character, presented in a side-facing, minimalistic style. Set against a plain sky blue background, the artwork uses a soft palette of brick red, denim blue, warm beige, and cream. Build the cap, face, gloves, shirt, overalls, arms, legs, and shoes from overlapping rounded geometric shapes with visible depth: separated parts, contact shadows, simple cel-shaded planes, and subtle edge highlights. The light source comes from slightly above and to the right, creating brighter upper-right edges and muted lower-left shadow shapes. Clean balanced spacing, playful geometric charm, no text, no logo, no watermark.
A layered 2.5D flat design illustration of a young wizard holding a wand, presented in a front-facing, minimalistic style. Set against a plain soft gray background, the artwork uses a soft palette of burgundy, warm beige, charcoal, and muted gold. Build the hair, glasses, robe, scarf, hands, wand, and shoes from overlapping rounded geometric shapes with visible depth: separated parts, contact shadows, simple cel-shaded planes, and subtle edge highlights. The light source comes from slightly above and to the right, creating brighter upper-right edges and muted lower-left shadow shapes. Clean balanced spacing, simple geometric charm, no text, no logo, no watermark.
视觉原则
- 主体占画面中心，轮廓清晰；动物和物品多用正面，动态人物可用侧面或三分之四视角。
- 使用大色块、圆角、简单几何形；光影也用清晰色块表达，不走写实纹理。
- 保留层次：分离部件、叠放色面、接触阴影、右上高光、左下暗面。
- 背景保持纯色或非常轻的明暗变化，不加复杂环境和透视空间。
- 调色以 2-3 个主色为核心，可加同色系明暗面来塑造厚度。
- 避免写实细节、文字、水印、复杂道具、过度装饰和强 3D 渲染感。
