# Design Brief: Dark Developer (with Gradient Glow)

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

## Design Tokens

```css
:root {
  --background: #12141c;
  --surface: #252836;
  --foreground: #ffffff;
  --muted-foreground: #a8aebc;
  --accent: #6fd4f0;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #12141C (~52%) · Surface #252836 (~22%) · Text #FFFFFF (~10%) · Muted Text #A8AEBC (~8%) · Accent #6FD4F0 (~8%). 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; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Code & Terminal
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring headline over large product shot 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.
