# Design Brief: Enterprise Clean (with 3D Tactile)
Trustworthy blue-anchored palette, structured grids, and prominent customer logo walls.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #f1f5f9;
--foreground: #080a13;
--muted-foreground: #535c66;
--accent: #058765;
--radius: 8px;
--font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
--font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~72%) · Surface #F1F5F9 (~16%) · Text #080A13 (~4%) · Muted Text #535C66 (~5%) · Accent #058765 (~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: 3D Render / Tactile Object
- Conversion CTA: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Direct Action Command
- Hero components: Custom Illustration, Customer Logo Wall
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and customer / press logo strip.
- Visual summary: Enterprise Clean (Light canvas, balanced density) featuring split copy & visual layout and 3d render / tactile object 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.
