# Hard Prompt
请严格遵守以下风格规则并保持一致性,禁止风格漂移。
## 执行要求
- 优先保证风格一致性,其次再做创意延展。
- 遇到冲突时以禁止项为最高优先级。
- 输出前自检:颜色、排版、间距、交互是否仍属于该风格。
## Style Rules
# Holy Grail Layout (圣杯布局) Design System
> 经典的三栏式网页布局,由固定页头、三列中间区域(左侧导航、主内容、右侧边栏)和固定页脚组成,是Web设计的基础布局范式。
## 核心理念
Holy Grail Layout 是Web设计中追求已久的经典布局方案,包含固定的页头页脚和三列中间内容区。这个名字来源于CSS布局早期实现这种布局的困难程度。
核心理念:
- 结构清晰:页头、三列内容、页脚五个区域各司其职
- 主内容优先:HTML 源码中主内容先于侧边栏,利于 SEO
- 等高列:三列无论内容多少都保持等高
- 灵活适配:侧边栏固定宽度,主内容区自适应
设计原则:
- 视觉一致性:所有组件必须遵循统一的视觉语言,从色彩到字体到间距保持谐调
- 层次分明:通过颜色深浅、字号大小、留白空间建立清晰的信息层级
- 交互反馈:每个可交互元素都必须有明确的 hover、active、focus 状态反馈
- 响应式适配:设计必须在移动端、平板、桌面端上保持一致的体验
- 无障碍性:确保色彩对比度符合 WCAG 2.1 AA 标准,所有交互元素可键盘访问

## [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-none`
- `shadow-2xl`
- `font-black`
- `font-extrabold`
- `text-5xl`
- `text-6xl`
- `text-7xl`
- `text-8xl`
### 禁止的模式
- 匹配 `^rounded-none$`
- 匹配 `^shadow-2xl`
- 匹配 `^text-[5-8]xl`
### 禁止原因
- `rounded-none`: Holy Grail Layout uses moderate rounding (rounded-xl) for a professional look
- `shadow-2xl`: Holy Grail Layout uses subtle shadows befitting a standard web layout
- `text-6xl`: Holy Grail Layout uses moderate type sizes for balanced three-column reading
> WARNING: 如果你的代码中包含以上任何 class,必须立即替换。

## [COMPARE] 错误 vs 正确对比
### 按钮
[WRONG] **错误示例**(使用了圆角和模糊阴影):
```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-lg font-medium text-sm transition-colors bg-[#ff006e] text-white px-4 py-2 md:px-6 md:py-3">
点击我
</button>
```
### 卡片
[WRONG] **错误示例**(使用了渐变和圆角):
```html
<div class="rounded-xl shadow-2xl bg-gradient-to-r from-purple-500 to-pink-500 p-6">
<h3 class="text-xl font-semibold">标题</h3>
</div>
```
[CORRECT] **正确示例**(纯色背景、硬边缘阴影):
```html
<div class="bg-white rounded-xl shadow-sm border border-gray-100 p-4 md:p-6">
<h3 class="font-semibold tracking-tight text-base md:text-lg">标题</h3>

```html
<input class="rounded-md border border-gray-300 px-3 py-2 focus:ring-2 focus:ring-blue-500" />
```
[CORRECT] **正确示例**(黑色粗边框、聚焦阴影):
```html
<input class="bg-gray-50 border border-gray-200 rounded-lg text-sm focus:outline-none focus:ring-2 focus:ring-[#3b82f6]/20 focus:border-[#3b82f6] transition-all px-3 py-2 md:px-4 md:py-3" placeholder="请输入..." />
