# Design Brief: Dark Developer (with Gradient Glow)

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

## Design Tokens

```css
:root {
  --background: #030312;
  --surface: #192533;
  --foreground: #fcfcfc;
  --muted-foreground: #dedede;
  --accent: #0090ff;
  --radius: 9999px;
  --font-heading: "Space Grotesk", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Avenir", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Geist Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #030312 (~77%) · Surface #192533 (~9%) · Text #FCFCFC (~6%) · Muted Text #DEDEDE (~4%) · Accent #0090FF (~4%). 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: Pill; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Large Hero Product Shot, Metrics Strip, Interactive Hero Tool
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with start free / sign up CTA and user count, rating, or key metrics.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring headline over large product shot layout and interactive hero demo / tool 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.
