# Design Brief: Dark Developer (with Minimal Monochrome)

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

## Design Tokens

```css
:root {
  --background: #0a0a0a;
  --surface: #1b1b1b;
  --foreground: #f5f5f2;
  --muted-foreground: #a3a3a3;
  --accent: #00bfdf;
  --radius: 4px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "IBM Plex Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #0A0A0A (~86%) · Surface #1B1B1B (~5%) · Text #F5F5F2 (~4%) · Muted Text #A3A3A3 (~3%) · Accent #00BFDF (~2%). 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; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Direct Action Command
- Hero components: Floating Multi-Cards, Customer Logo Wall
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and customer / press logo strip.
- Visual summary: Dark Developer (Dark canvas, airy density) featuring centered headline + cta layout and illustration / character art 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.
