# Kraken 启发的设计系统

## 1. 视觉主题与氛围

Kraken 的网站是一个干净、可信的加密货币交易平台，使用紫色作为强势品牌色。设计运行在白色背景之上，通过 Kraken Purple (`#7132f5`, `#5741d8`, `#5b1ecf`) 建立鲜明且专业的 crypto identity。专有的 Kraken-Brand 字体负责 display heading，使用 bold (700) weight 和 negative tracking；Kraken-Product（以 IBM Plex Sans 作为 fallback）则承担 UI 主力字体角色。

**Key Characteristics:**
- Kraken Purple (`#7132f5`) 作为 primary brand，并配合更深的变体 (`#5741d8`, `#5b1ecf`)
- Kraken-Brand (display) + Kraken-Product (UI) 的双字体系统
- Near-black (`#101114`) 文本，搭配冷调 blue-gray neutral scale
- 12px radius button（圆角，但不是 pill）
- Subtle shadow (`rgba(0,0,0,0.03) 0px 4px 24px`)，轻到接近耳语级
- Green accent (`#149e61`) 用于 positive/success state
