# Design Brief: Soft & Friendly

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

## Design Tokens

```css
:root {
  --background: #f6f3ea;
  --surface: #dce8d0;
  --foreground: #2a2a2a;
  --muted-foreground: #6b6b6b;
  --accent: #1f6b2c;
  --radius: 4px;
  --font-heading: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F6F3EA (~42%) · Surface #DCE8D0 (~22%) · Text #2A2A2A (~16%) · Muted Text #6B6B6B (~8%) · Accent #1F6B2C (~12%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Split Copy & Visual
- Navigation: Left App Sidebar
- Theme & density: Light · Dense
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Outcome & Speed Promise
- Hero components: Custom Illustration
- Spatial layout notes: Split Copy & Visual hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Soft & Friendly (Light canvas, dense density) featuring split copy & visual 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.
