# Design Brief: Enterprise Clean

Trustworthy blue-anchored palette, structured grids, and prominent customer logo walls.

## Design Tokens

```css
:root {
  --background: #f7f8f8;
  --surface: #ffffff;
  --foreground: #222222;
  --muted-foreground: #858b89;
  --accent: #123e8a;
  --radius: 0px;
  --font-heading: "Noto Serif JP", serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F7F8F8 (~66%) · Surface #FFFFFF (~12%) · Text #222222 (~12%) · Muted Text #858B89 (~7%) · Accent #123E8A (~3%). 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: Sharp; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Book Demo / Contact Sales · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Category Positioning Anchor
- Hero components: Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with book demo / contact sales CTA and stacked avatars & testimonials.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring centered headline + cta layout and photography / live video visuals.

## Avoid

- Experimental navigation patterns
- Low-legibility decorative fonts
- Visual novelty that obscures the value proposition

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.
