# 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: #f4f6f8;
  --foreground: #1c1c1c;
  --muted-foreground: #5c6570;
  --accent: #1a73e8;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~58%) · Surface #F4F6F8 (~18%) · Text #1C1C1C (~8%) · Muted Text #5C6570 (~6%) · Accent #1A73E8 (~10%). 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: Illustration / Character Art
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Category Positioning Anchor
- Hero components: Video Demo, Custom Illustration
- Spatial layout notes: Split Copy & Visual hero structure paired with direct input / instant try CTA and stacked avatars & testimonials.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring split copy & visual layout and illustration / character art 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.
