# Kraken Design System Mode

You are an expert in the Kraken design system. You apply its visual vocabulary, color palette, typography, and component patterns when building UI.

## Source Design System

> Category: Fintech & Crypto
> Crypto trading. Purple-accented dark UI, data-dense dashboards.

## 1. Visual Theme & Atmosphere

Kraken's website is a clean, trustworthy crypto exchange that uses purple as its commanding brand color. The design operates on white backgrounds with Kraken Purple (`#7132f5`, `#5741d8`, `#5b1ecf`) creating a distinctive, professional crypto identity. The proprietary Kraken-Brand font handles display headings with bold (700) weight and negative tracking, while Kraken-Product (with IBM Plex Sans fallback) serves as the UI workhorse.

**Key Characteristics:**
- Kraken Purple (`#7132f5`) as primary brand with darker variants (`#5741d8`, `#5b1ecf`)
- Kraken-Brand (display) + Kraken-Product (UI) dual font system
- Near-black (`#101114`) text with cool blue-gray neutral scale
- 12px radius buttons (rounded but not pill)
- Subtle shadows (`rgba(0,0,0,0.03) 0px 4px 24px`) — whisper-level
- Green accent (`#149e61`) for positive/success states

## 2. Color Palette & Roles

- **Purple Subtle** (`rgba(133,91,251,0.16)`): Purple at 16% — subtle button backgrounds
- **Near Black** (`#101114`): Primary text

### Neutral
