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

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f4f6f8;
  --foreground: #111111;
  --muted-foreground: #8a93a0;
  --accent: #f59a23;
  --radius: 8px;
  --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 (~72%) · Surface #F4F6F8 (~8%) · Text #111111 (~8%) · Muted Text #8A93A0 (~6%) · Accent #F59A23 (~6%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Avoid

- Harsh pure-black backgrounds
- Sharp 0px corners
- Cold technical jargon in hero copy

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
