# Design Brief: Dark Developer
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #000000;
--surface: #1c1c1c;
--foreground: #f2f2f2;
--muted-foreground: #8a8a8a;
--accent: #22d3ee;
--radius: 4px;
--font-heading: "JetBrains Mono", ui-monospace, monospace;
--font-body: "JetBrains Mono", ui-monospace, monospace;
--font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #000000 (~72%) · Surface #1C1C1C (~14%) · Text #F2F2F2 (~6%) · Muted Text #8A8A8A (~4%) · Accent #22D3EE (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
