# Design Brief: Dark Developer (with Gradient Glow)

Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.

## Design Tokens

```css
:root {
  --background: #0d1727;
  --surface: #ffffff;
  --foreground: #f5f7fa;
  --muted-foreground: #aeb9c7;
  --accent: #10b981;
  --radius: 16px;
  --font-heading: "Barlow", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Public Sans Variable", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #0D1727 (~48%) · Surface #FFFFFF (~28%) · Text #F5F7FA (~13%) · Muted Text #AEB9C7 (~7%) · Accent #10B981 (~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: 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: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Interactive Hero Tool, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and live generated output showcase.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component visuals.

## Avoid

- Warm pastel backgrounds
- Playful cartoon illustrations
- Oversized pill buttons everywhere

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.
