# Design Brief: Hand-Drawn & Sketch (with Soft & Friendly)

Handwritten display accents, doodle annotations, and sketch-style illustrations.

## Design Tokens

```css
:root {
  --background: #eee9fc;
  --surface: #ffffff;
  --foreground: #15121a;
  --muted-foreground: #77727f;
  --accent: #8b26e8;
  --radius: 8px;
  --font-heading: "手書き風日本語書体", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #EEE9FC (~65%) · Surface #FFFFFF (~17%) · Text #15121A (~8%) · Muted Text #77727F (~4%) · Accent #8B26E8 (~6%). 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: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Hand-Drawn & Sketch (Light canvas, balanced density) featuring centered headline + cta layout and illustration / character art visuals.

## Avoid

- Rigid corporate stock photography
- Heavy 3D metallic renders
- Overly dense enterprise dashboards

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.
