# Design Brief: Gradient Glow (with Enterprise Clean)

Luminous radial glows and translucent glass panels, widely used across modern AI products.

## Design Tokens

```css
:root {
  --background: #0b1026;
  --surface: #171c32;
  --foreground: #f4f5fa;
  --muted-foreground: #b6bed4;
  --accent: #7662ff;
  --radius: 8px;
  --font-heading: "Roboto", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #0B1026 (~72%) · Surface #171C32 (~12%) · Text #F4F5FA (~8%) · Muted Text #B6BED4 (~5%) · Accent #7662FF (~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: Dark · Balanced
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: 3D Render / Tactile Object
- Conversion CTA: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Target Audience Callout
- Hero components: Metrics Strip, 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: Gradient Glow (Dark canvas, balanced density) featuring split copy & visual layout and 3d render / tactile object visuals.

## Avoid

- Muddy low-contrast text over gradients
- Overuse of full-screen rainbow backgrounds
- Cluttered dense tables in the hero

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.
