# Design Brief: Soft & Friendly (with Enterprise Clean)

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f3f3f3;
  --foreground: #0a0a0a;
  --muted-foreground: #777777;
  --accent: #0067e6;
  --radius: 16px;
  --font-heading: "Segoe UI Symbol", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Segoe UI Symbol", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~74%) · Surface #F3F3F3 (~15%) · Text #0A0A0A (~6%) · Muted Text #777777 (~3%) · Accent #0067E6 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + Input
- Navigation: Left App Sidebar
- Theme & density: Light · Balanced
- Border radius & elevation: Large Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Direct Action Command
- Hero components: Centered Prompt / Input, Interactive Hero Tool, Floating Multi-Cards
- Spatial layout notes: Centered Headline + Input hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Soft & Friendly (Light canvas, balanced density) featuring centered headline + input layout and product ui screenshot / component 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.
