# Design Brief: Soft & Friendly (with Minimal Monochrome)

Warm low-saturation pastels, generous rounded corners, and approachable illustrations.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f0fdf4;
  --foreground: #0a0a0a;
  --muted-foreground: #737373;
  --accent: #16a34a;
  --radius: 9999px;
  --font-heading: "Noto Sans", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~78%) · Surface #F0FDF4 (~8%) · Text #0A0A0A (~7%) · Muted Text #737373 (~4%) · Accent #16A34A (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
