Opinionated constraints for building Launchdarkly-style interfaces with AI agents.

为使用AI Agent构建Launchdarkly风格界面而制定的约束性指南。

When to Apply

适用场景

Reference these guidelines when:

Building dark-mode interfaces
Creating Launchdarkly-inspired design systems
Implementing UIs with Inter font and 4px grid

参考以下指南的场景：

构建深色模式界面时
创建受Launchdarkly启发的设计系统时
实现采用Inter字体和4px网格的UI时

Colors

色彩规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 0
MUST use
```
#000000
```
as page background (
```
surface-base
```
)
MUST use
```
#AAB7F5
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 13 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面必须使用深色背景（亮度<20）——当前检测到的亮度为0
页面背景必须使用
```
#000000
```
（对应语义令牌
```
surface-base
```
）
主要操作和焦点状态必须使用
```
#AAB7F5
```
（对应语义令牌
```
accent
```
）
应精简调色板（当前检测到13种颜色）
为保证可访问性，文本对比度必须至少达到4.5:1

SHOULD maintain consistent padding within containers

必须使用4px网格系统来设置间距
应使用以下间距刻度值：4px, 5px, 7px, 9px, 12px, 21px, 28px, 69px
元素间默认间距应使用4px
不得使用任意间距值（需遵循设计刻度）

```
h-screen
```
, use
```

SHOULD use
```
size-*
```
for square elements instead of
```

不得使用
```
h-screen
```
，应使用
```
h-dvh
```

固定元素必须考虑
```
safe-area-inset
```
（安全区域内边距）
方形元素应使用
```
size-*
```
