# Design Brief: Enterprise Clean (with Minimal Monochrome)
Trustworthy blue-anchored palette, structured grids, and prominent customer logo walls.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #eff6ff;
--foreground: #111111;
--muted-foreground: #6b6b6b;
--accent: #5341e5;
--radius: 8px;
--font-heading: "Roboto", ui-sans-serif, system-ui, sans-serif;
--font-body: "Roboto", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~74%) · Surface #EFF6FF (~16%) · Text #111111 (~4%) · Muted Text #6B6B6B (~3%) · Accent #5341E5 (~3%). 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: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Category Positioning Anchor
- Hero components: Interactive Hero Tool, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with direct input / instant try CTA and user count, rating, or key metrics.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring split copy & visual layout and interactive hero demo / tool 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.
