# Design Brief: Gradient Glow (with Dark Developer)

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

## Design Tokens

```css
:root {
  --background: #0b1437;
  --surface: #ffffff;
  --foreground: #ffffff;
  --muted-foreground: #dfe4f5;
  --accent: #d4145a;
  --radius: 16px;
  --font-heading: "Plus Jakarta Sans Variable", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter Variable", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono Variable", ui-monospace, monospace;
}
```

Color area ratio: Background #0B1437 (~55%) · Surface #FFFFFF (~30%) · Text #FFFFFF (~7%) · Muted Text #DFE4F5 (~5%) · Accent #D4145A (~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: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Start Free / Sign Up · Trust bar uses Live Generated Output Showcase
- Headline hook: Pain Relief & Replacement
- Hero components: Large Hero Product Shot, Floating Multi-Cards, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and live generated output showcase.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component 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.
