# Design Brief: Soft & Friendly

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f7f9fc;
  --foreground: #222222;
  --muted-foreground: #8a93a3;
  --accent: #1e6ad6;
  --radius: 16px;
  --font-heading: "Noto Sans SC", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans SC", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~40%) · Surface #F7F9FC (~22%) · Text #222222 (~14%) · Muted Text #8A93A3 (~8%) · Accent #1E6AD6 (~16%). 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: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Pain Relief & Replacement
- Hero components: Centered Prompt / Input
- Spatial layout notes: Centered Headline + Input hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Soft & Friendly (Light canvas, balanced density) featuring centered headline + input layout and interactive hero demo / tool 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.
