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

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

## Design Tokens

```css
:root {
  --background: #fafaf9;
  --surface: #ffffff;
  --foreground: #1a1a1a;
  --muted-foreground: #78716c;
  --accent: #3e2bf6;
  --radius: 16px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FAFAF9 (~80%) · Surface #FFFFFF (~7%) · Text #1A1A1A (~6%) · Muted Text #78716C (~4%) · Accent #3E2BF6 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase
- Headline hook: Outcome & Speed Promise
- Hero components: Floating Multi-Cards, Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and live generated output showcase.
- Visual summary: Soft & Friendly (Light canvas, balanced density) featuring centered headline + cta layout and illustration / character art visuals.

## 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.
