几何大胆风

# Geometric Bold (几何大胆风) Design System

> 大胆的几何图形设计，强烈的形状对比、鲜明的色块、动态的构图。适合艺术展览、设计机构、创意品牌。

## 核心理念

Geometric Bold 风格受包豪斯和构成主义艺术的影响，通过简单但强烈的几何形状创造视觉冲击。

核心理念：
- 形状优先：几何形状是设计的核心语言
- 大胆对比：强烈的颜色和形状对比
- 动态平衡：通过不对称创造视觉张力
- 艺术表达：每个页面都是一件艺术品

  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-none border-2 md:border-4 border-black shadow-[4px_4px_0px_0px_rgba(0,0,0,1)] md:shadow-[8px_8px_0px_0px_rgba(0,0,0,1)] hover:shadow-none hover:translate-x-[2px] hover:translate-y-[2px] transition-all duration-200 font-black bg-[#ff006e] text-white px-4 py-2 md:px-6 md:py-3">
