# 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
# Split Screen (分屏布局) Design System

> 左右对称或不对称的分屏布局，通过对比和平衡创造视觉张力，常用于产品展示、品牌故事、比较页面。

## 核心理念

Split Screen（分屏布局）是一种将视口分为两个或多个区域的布局方式，通过对比创造视觉张力和叙事效果。

核心理念：
- 对比强调：通过左右对比突出差异或联系
- 视觉平衡：即使不对称也保持视觉重量平衡
- 叙事引导：引导用户视线在两侧之间流动
- 空间利用：充分利用宽屏显示器的优势

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-lg`
- `rounded-xl`
- `rounded-2xl`
- `rounded-full`
- `shadow-sm`
- `shadow-md`
- `shadow-lg`
- `shadow-xl`

### 禁止的模式
- 匹配 `^rounded-(?!none)`
- 匹配 `^shadow-(?!none)`

### 禁止原因
- `rounded-lg`: Split Screen uses sharp edges for strong visual dividers
- `shadow-lg`: Split Screen relies on contrast between panels, not shadows

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

# Soft Prompt

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

## Style Signals
- 分屏
- 对比
- 左右布局
- 对称
- 品牌
- 展示

## Prefer
- Use CSS Grid or Flexbox for split screen grid grid-cols-2
- Large screens maintain split, small screens stack lg:grid-cols-2 grid-cols-1
- Use contrasting or complementary content
- Visual elements on one side, text content on the other

## Avoid
- Do not have identical content on both sides (pointless split)
- Do not keep split layout on mobile (too narrow)
- Do not create severe visual weight imbalance between sides

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