# Hard Prompt

Strictly follow the style rules below and maintain consistency. No style drift allowed.

## Requirements
- Prioritize style consistency first, then creative extension.
- When conflicts arise, treat prohibitions as the highest priority.
- Self-check before output: verify colors, typography, spacing, and interactions still match this style.

## Style Rules
# Cubism (立体主义) Design System

> 毕加索和布拉克的立体主义运动，几何碎片化构图、多视角叠加、棱角分明的形状与沉稳的大地色调。

## 核心理念

Cubism（立体主义）是20世纪最具革命性的艺术运动之一，由毕加索和布拉克于1907年前后开创。它彻底打破了文艺复兴以来的单点透视传统，用几何碎片和多视角叠加重新定义了视觉表达。

核心理念：
- 几何碎片化：将物体分解为基本几何形状——三角形、矩形、不规则多边形
- 多视角叠加：同一画面呈现物体的多个角度，打破单一视点的限制
- 大地色调：棕色、赭石、灰蓝的沉稳配色，源自分析立体主义时期的克制用色
- 棱角与张力：通过锐利的边缘和不对称构图创造视觉张力

在数字设计中，立体主义风格适用于艺术画廊、创意机构、文化活动和高端品牌。它传达的是知性、前卫和对传统的挑战精神。

设计时应注重几何元素的层叠与交错，通过不同角度的平面暗示深度，而非使用传统的透视或阴影。色彩克制但构图大胆，这是立体主义的核心矛盾与魅力所在。

## [FORBIDDEN] 绝对禁止

以下 class 在本风格中**绝对禁止使用**，生成时必须检查并避免：

### 禁止的 Class
- `rounded-2xl`
- `rounded-3xl`
- `rounded-full`
- `rounded-xl`
- `shadow-sm`
- `shadow-md`
- `shadow-lg`
- `bg-gradient-to-r`
- `bg-gradient-to-br`
- `text-[#ff00ff]`
- `text-[#00ffff]`
- `blur-sm`
- `blur-md`
- `blur-lg`
- `backdrop-blur`

### 禁止的模式
- 匹配 `^rounded-(?:xl|2xl|3xl|full)`
- 匹配 `^shadow-(?:sm|md|lg|xl)$`
- 匹配 `^bg-gradient`
- 匹配 `^blur-`
- 匹配 `^backdrop-blur`

### 禁止原因
- `rounded-2xl`: Cubism uses sharp angles and minimal rounding (rounded-sm only)
- `rounded-full`: Cubism rejects organic curves; use angular shapes
- `shadow-md`: Cubism uses hard-edge shadows (shadow-[Npx_Npx_0px_color]), not soft shadows
- `bg-gradient-to-r`: Cubism uses flat, opaque color planes without gradients
- `blur-sm`: Cubism uses crisp, hard edges; blur effects are forbidden

> WARNING: 如果你的代码中包含以上任何 class，必须立即替换。

```html
<button class="rounded-lg shadow-lg bg-blue-500 text-white px-4 py-2 hover:bg-blue-600">
  点击我
</button>
```

[CORRECT] **正确示例**（使用硬边缘、无圆角、位移效果）：
```html
<button class="rounded-sm font-bold uppercase tracking-widest border-2 shadow-[4px_4px_0px_#8b7355] transition-all duration-150 bg-[#ff006e] text-white px-4 py-2 md:px-6 md:py-3">

# Soft Prompt

Maintain the overall style essence. Implementation details can be adjusted flexibly, but do not deviate from the core visual language.

## Style Signals
- 立体主义
- 毕加索
- 几何
- 碎片
- 多视角
- 棱角

## Prefer
- Use angular geometric shapes with skew and rotate transforms
- Use earth-tone palette #5c4033 and #e8dcc8 as primary colors
- Use thick line borders border-2 paired with dark border colors
- Use small rounded corners rounded or rounded-sm to maintain angularity

## Avoid
- Do not use large rounded corners rounded-2xl, rounded-full
- Do not use soft gradients or blur effects
- Do not use neon or fluorescent colors

## Output Guidance
- Ensure overall style recognizability first, then refine details.
- Avoid over-engineering; maintain readability and maintainability.
