# Design Brief: Minimal Monochrome (with Soft & Friendly)
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #f4f6fa;
--foreground: #202127;
--muted-foreground: #8993a2;
--accent: #6555e8;
--radius: 16px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-mono: "Geist Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #FFFFFF (~79%) · Surface #F4F6FA (~8%) · Text #202127 (~7%) · Muted Text #8993A2 (~4%) · Accent #6555E8 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
