# Design Brief: Enterprise Clean

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #ffffff;
  --foreground: #20232b;
  --muted-foreground: #555960;
  --accent: #08082f;
  --radius: 4px;
  --font-heading: "Oswald", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~87%) · Surface #FFFFFF (~4%) · Text #20232B (~5%) · Muted Text #555960 (~2%) · Accent #08082F (~2%). 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 · Airy
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Direct Input / Instant Try

- Spatial layout notes: Editorial Serif Headline hero structure paired with direct input / instant try CTA and no explicit trust bar.

## 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.
