# Design Brief: Soft & Friendly
Warm low-saturation pastels, generous rounded corners, and approachable illustrations.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #f3f7fd;
--foreground: #07182f;
--muted-foreground: #777d85;
--accent: #3989ed;
--radius: 4px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~78%) · Surface #F3F7FD (~8%) · Text #07182F (~7%) · Muted Text #777D85 (~5%) · Accent #3989ED (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
