# Design Brief: Retro & Nostalgic

Pixel typography, classic OS window chrome, or warm vintage print palettes.

## Design Tokens

```css
:root {
  --background: #f8f8f8;
  --surface: #ffffff;
  --foreground: #30332f;
  --muted-foreground: #dee8dd;
  --accent: #247557;
  --radius: 4px;
  --font-heading: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Serif JP", serif;
}
```

Color area ratio: Background #F8F8F8 (~40%) · Surface #FFFFFF (~35%) · Text #30332F (~7%) · Muted Text #DEE8DD (~8%) · Accent #247557 (~10%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Editorial Serif Headline
- Navigation: Full-Width Top Bar
- Theme & density: Light · Dense
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Category Positioning Anchor
- Hero components: Custom Illustration, Interactive Hero Tool
- Spatial layout notes: Editorial Serif Headline hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Retro & Nostalgic (Light canvas, dense density) featuring editorial serif headline layout and illustration / character art visuals.

## Avoid

- Generic modern corporate gradients
- Inconsistent mixing of modern flat UI and retro chrome

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.
