# Design Brief: Enterprise Clean (with Soft & Friendly)

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f6f5f3;
  --foreground: #302e2d;
  --muted-foreground: #666666;
  --accent: #006838;
  --radius: 9999px;
  --font-heading: "gtAmerica", ui-sans-serif, system-ui, sans-serif;
  --font-body: "gtAmerica", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~80%) · Surface #F6F5F3 (~7%) · Text #302E2D (~6%) · Muted Text #666666 (~3%) · Accent #006838 (~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: Light · Airy
- Border radius & elevation: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Video Demo, Floating Multi-Cards
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Enterprise Clean (Light canvas, airy density) featuring split copy & visual layout and photography / live video 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.
