# Design Brief: Editorial (with Minimal Monochrome)

Oversized serif headlines, narrow reading columns, and magazine-inspired grid layouts.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f4f4f4;
  --foreground: #111111;
  --muted-foreground: #9a9a9a;
  --accent: #e24b4b;
  --radius: 9999px;
  --font-heading: "Noto Serif JP", serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~62%) · Surface #F4F4F4 (~16%) · Text #111111 (~12%) · Muted Text #9A9A9A (~5%) · Accent #E24B4B (~5%). 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 · Airy
- Border radius & elevation: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Book Demo / Contact Sales
- Headline hook: Brand Manifesto & Curiosity
- Spatial layout notes: Centered Headline + CTA hero structure paired with book demo / contact sales CTA and no explicit trust bar.

## Avoid

- Generic SaaS hero templates
- Cramped multi-column feature grids
- Neon cyber accents

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.
