# Design Brief: Gradient Glow (with Vibrant Pop)

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

## Design Tokens

```css
:root {
  --background: #080b18;
  --surface: #171a2a;
  --foreground: #ffffff;
  --muted-foreground: #d9dad2;
  --accent: #c9ff00;
  --radius: 9999px;
  --font-heading: "Castaly Lausanne", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Castaly Lausanne", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Geist Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #080B18 (~69%) · Surface #171A2A (~17%) · Text #FFFFFF (~6%) · Muted Text #D9DAD2 (~4%) · Accent #C9FF00 (~4%). 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: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Centered Prompt / Input, Large Hero Product Shot, Floating Multi-Cards
- Spatial layout notes: Split Copy & Visual hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring split copy & visual layout and photography / live video 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.
