# Design Brief: Dark Developer

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

## Design Tokens

```css
:root {
  --background: #1e2a3d;
  --surface: #27364b;
  --foreground: #f3f5f8;
  --muted-foreground: #aab5c5;
  --accent: #2d83e8;
  --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 #1E2A3D (~83%) · Surface #27364B (~4%) · Text #F3F5F8 (~7%) · Muted Text #AAB5C5 (~5%) · Accent #2D83E8 (~1%). 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 · Balanced
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up
- Headline hook: Target Audience Callout
- Hero components: Metrics Strip
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring centered headline + cta layout and photography / live video 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.
