# Design Brief: Enterprise Clean (with Dark Developer)

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

## Design Tokens

```css
:root {
  --background: #f4f6f8;
  --surface: #ffffff;
  --foreground: #31546e;
  --muted-foreground: #858d95;
  --accent: #328fc5;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #F4F6F8 (~58%) · Surface #FFFFFF (~8%) · Text #31546E (~14%) · Muted Text #858D95 (~12%) · Accent #328FC5 (~8%). 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: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Category Positioning Anchor
- Hero components: Code & Terminal, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and user count, rating, or key metrics.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring split copy & visual layout and code block / terminal / cli 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.
