# Design Brief: Enterprise Clean

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #5074e8;
  --foreground: #333333;
  --muted-foreground: #8f8f8f;
  --accent: #5074e8;
  --radius: 8px;
  --font-heading: "Helvetica Neue For Number", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Helvetica Neue For Number", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~78%) · Surface #5074E8 (~9%) · Text #333333 (~6%) · Muted Text #8F8F8F (~4%) · Accent #5074E8 (~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 · Airy
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Book Demo / Contact Sales
- Headline hook: Category Positioning Anchor
- Spatial layout notes: Centered Headline + CTA hero structure paired with book demo / contact sales CTA and no explicit trust bar.
- Visual summary: Enterprise Clean (Light canvas, airy density) featuring centered headline + cta layout and pure typography & geometry 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.
