# Design Brief: Dark Developer (with Gradient Glow)

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

## Design Tokens

```css
:root {
  --background: #25262a;
  --surface: #2e3034;
  --foreground: #d5d4d6;
  --muted-foreground: #a5a3a7;
  --accent: #dba145;
  --radius: 4px;
  --font-heading: "Montserrat", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Montserrat", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #25262A (~77%) · Surface #2E3034 (~7%) · Text #D5D4D6 (~5%) · Muted Text #A5A3A7 (~3%) · Accent #DBA145 (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Airy
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Customer / Press Logo Strip
- Headline hook: Outcome & Speed Promise
- Hero components: Customer Logo Wall, Large Hero Product Shot
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and customer / press logo strip.
- Visual summary: Dark Developer (Dark canvas, airy density) featuring centered headline + cta 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.
