# Design Brief: Soft & Friendly (with Minimal Monochrome)
Warm low-saturation pastels, generous rounded corners, and approachable illustrations.
## Design Tokens
```css
:root {
--background: #f7f9ee;
--surface: #e6e9dd;
--foreground: #0e2000;
--muted-foreground: #44483d;
--accent: #3f6300;
--radius: 9999px;
--font-heading: "Instrument Sans", ui-sans-serif, system-ui, sans-serif;
--font-body: "Instrument Sans", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #F7F9EE (~80%) · Surface #E6E9DD (~7%) · Text #0E2000 (~6%) · Muted Text #44483D (~4%) · Accent #3F6300 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
