# 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
# Data Dense (数据密集) Design System

> 高密度后台管理面板风格，紧凑间距与小尺寸组件，优先展示数据表格与操作效率。

## 核心理念

Data Dense 是一种效率优先的管理界面设计语言。

核心理念：
- 信息密度最大化：在有限屏幕空间内展示最多有效信息
- 扫描效率：行高紧凑、对齐严格，支持快速垂直扫描
- 操作即时性：行内操作、快捷键、批量选择减少点击次数
- 状态可视化：颜色编码传递状态，无需阅读文字即可理解

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-xl`
- `rounded-2xl`
- `shadow-lg`
- `shadow-xl`
- `shadow-2xl`
- `p-6`
- `p-8`
- `text-lg`
- `text-xl`
- `text-2xl`

### 禁止的模式
- 匹配 `^rounded-(xl|2xl|3xl|full)`
- 匹配 `^shadow-(lg|xl|2xl)`
- 匹配 `^p-[6-9]`
- 匹配 `^bg-gradient-`

### 禁止原因
- `rounded-xl`: Data Dense uses small rounded corners only
- `shadow-lg`: Data Dense avoids decorative shadows
- `p-6`: Data Dense uses compact spacing (p-3 or less)
- `text-lg`: Data Dense uses small text sizes (text-sm or text-xs)

> 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="px-2.5 py-1 text-xs rounded 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 border border-[#e2e8f0] rounded px-3 py-2.5">
  <h3 class="font-semibold tracking-tight text-sm md:text-base">标题</h3>

```

[CORRECT] **正确示例**（黑色粗边框、聚焦阴影）：

# Soft Prompt

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

## Style Signals
- 后台管理
- 数据表格
- 高密度
- 管理面板
- 运营
- admin

## Prefer
- Use white bg-white with very light blue-gray bg-[#f8fafc] alternating rows
- Table rows use compact py-2 text-sm or text-xs
- Status badges use color coding bg-blue-50 text-blue-700 rounded px-1.5 py-0.5 text-xs
- Buttons use small size px-2.5 py-1 text-xs rounded

## Avoid
- Never use large spacing p-6+ (wastes data display space)
- Never use large rounded-xl+ corners (wastes pixels)
- Never use large text-lg+ for table data

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