# Design Brief: Dark Developer (with Minimal Monochrome)

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

## Design Tokens

```css
:root {
  --background: #0f1719;
  --surface: #1c2529;
  --foreground: #e8eef0;
  --muted-foreground: #8b9a9e;
  --accent: #5bc4d9;
  --radius: 0px;
  --font-heading: "Space Grotesk", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Plus Jakarta Sans", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #0F1719 (~80%) · Surface #1C2529 (~8%) · Text #E8EEF0 (~6%) · Muted Text #8B9A9E (~3%) · Accent #5BC4D9 (~3%). 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 · Dense
- Border radius & elevation: Sharp; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Direct Input / Instant Try · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with direct input / instant try CTA and user count, rating, or key metrics.
- Visual summary: Dark Developer (Dark canvas, dense 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.
