# 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: #17172d;
  --surface: #29164a;
  --foreground: #ffffff;
  --muted-foreground: #d7d3e2;
  --accent: #f2c900;
  --radius: 8px;
  --font-heading: "system-ui", ui-sans-serif, system-ui, sans-serif;
  --font-body: "system-ui", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #17172D (~54%) · Surface #29164A (~18%) · Text #FFFFFF (~8%) · Muted Text #D7D3E2 (~7%) · Accent #F2C900 (~13%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Headline Over Large Product Shot
- 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: Product UI Screenshot / Component
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Direct Action Command
- Hero components: Interactive Hero Tool, Large Hero Product Shot, Floating Multi-Cards
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring headline over large product shot 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.
