# Design Brief: Enterprise Clean (with Minimal Monochrome)

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

## Design Tokens

```css
:root {
  --background: #14181c;
  --surface: #ffffff;
  --foreground: #ffffff;
  --muted-foreground: #aeb7bd;
  --accent: #165eee;
  --radius: 16px;
  --font-heading: "Host Grotesk", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Host Grotesk", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #14181C (~59%) · Surface #FFFFFF (~27%) · Text #FFFFFF (~6%) · Muted Text #AEB7BD (~4%) · Accent #165EEE (~4%). 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: Dark · Balanced
- Border radius & elevation: Large Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Customer Logo Wall
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and customer / press logo strip.
- Visual summary: Enterprise Clean (Dark 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.
