# Design Brief: Enterprise Clean

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f5f5f5;
  --foreground: #222222;
  --muted-foreground: #666666;
  --accent: #f9a43b;
  --radius: 4px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~65%) · Surface #F5F5F5 (~10%) · Text #222222 (~12%) · Muted Text #666666 (~8%) · Accent #F9A43B (~5%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component 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.
