# Design Brief: Dark Developer (with Editorial)
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #131411;
--surface: #fafbfc;
--foreground: #f0efeb;
--muted-foreground: #97988f;
--accent: #f3d168;
--radius: 4px;
--font-heading: "Instrument Serif", serif;
--font-body: "Instrument Serif", serif;
--font-mono: "IBM Plex Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #131411 (~48%) · Surface #FAFBFC (~41%) · Text #F0EFEB (~6%) · Muted Text #97988F (~4%) · Accent #F3D168 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Book Demo / Contact Sales · Trust bar uses Customer / Press Logo Strip
- Headline hook: Target Audience Callout
- Hero components: Large Hero Product Shot, Customer Logo Wall
- Spatial layout notes: Split Copy & Visual hero structure paired with book demo / contact sales CTA and customer / press logo strip.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring split copy & visual 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.
