# Design Brief: Enterprise Clean (with Minimal Monochrome)

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

## Design Tokens

```css
:root {
  --background: #d8d8d8;
  --surface: #ffffff;
  --foreground: #111111;
  --muted-foreground: #a7a7a7;
  --accent: #0098b8;
  --radius: 0px;
  --font-heading: "Oswald", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #D8D8D8 (~72%) · Surface #FFFFFF (~16%) · Text #111111 (~6%) · Muted Text #A7A7A7 (~4%) · Accent #0098B8 (~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 · Dense
- Border radius & elevation: Sharp; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Metrics Strip
- Spatial layout notes: Editorial Serif Headline hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Enterprise Clean (Light canvas, dense density) featuring editorial serif headline 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.
