## System Prompt (paste into AI agent)

```
Arbitrum's design is a premium, high-contrast fintech identity defined by bold, uppercase typography and a stark navy-and-white palette. The primary accent is a vivid cyan (#10E1FF), used for emphasis against a deep navy (#05163D) background. The typography is exclusively sans-serif, with a grotesque-sans display font for hero sections and a geometric-sans for body text, all set in medium (500) or semibold (600) weights and uppercase by default. Layouts are spacious and grid-based, with generous padding and clear hierarchy. Key donts: do not use lowercase navigation, do not use light font weights, do not use a pastel palette, do not use serif fonts, do not use cluttered layouts, and do not use thin borders or outlines without sufficient contrast.
