## System Prompt (paste into AI agent)

```
This design system for Browserbase is a high-contrast, developer-focused interface. It uses a palette of neutral off-whites and creams (#F1F0EC, #FFFACD) with deep black text (#000000) and a vibrant orange accent (#FF5500). Typography is centered around modern grotesque-sans for display and body, with monospace fonts for technical snippets. Critical constraints include avoiding soft pastels, excessive rounded corners, and decorative serifs. The layout is centered and dense, using a 4px grid and generous vertical spacing. Ensure all interactive elements have smooth, snappy transitions using a custom cubic-bezier easing curve. Maintain a direct, technical voice in all copy.
