# Design Brief: Dark Developer (with Minimal Monochrome)

Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.

## Design Tokens

```css
:root {
  --background: #050506;
  --surface: #111114;
  --foreground: #f4f4f6;
  --muted-foreground: #a3a3aa;
  --accent: #1260f5;
  --radius: 9999px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #050506 (~83%) · Surface #111114 (~4%) · Text #F4F4F6 (~6%) · Muted Text #A3A3AA (~4%) · Accent #1260F5 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Avoid

- Warm pastel backgrounds

- Oversized pill buttons everywhere

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
