# Design Brief: Dark Developer
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #0b0d12;
--surface: #161a23;
--foreground: #e6e9ef;
--muted-foreground: #9299a8;
--accent: #08c995;
--radius: 8px;
--font-heading: "Geist Mono", ui-monospace, monospace;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-mono: "Geist Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #0B0D12 (~70%) · Surface #161A23 (~18%) · Text #E6E9EF (~5%) · Muted Text #9299A8 (~5%) · Accent #08C995 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
