# Design Brief: Dark Developer (with Gradient Glow)

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

## Design Tokens

```css
:root {
  --background: #071718;
  --surface: #0d2929;
  --foreground: #f3f5f5;
  --muted-foreground: #b7c6c8;
  --accent: #55c4f4;
  --radius: 9999px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #071718 (~78%) · Surface #0D2929 (~6%) · Text #F3F5F5 (~8%) · Muted Text #B7C6C8 (~4%) · Accent #55C4F4 (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
