# Design Brief: Dark Developer (with Editorial)
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #000000;
--surface: #ffffff;
--foreground: #f8f8f8;
--muted-foreground: #777777;
--accent: #0045ff;
--radius: 4px;
--font-heading: "Merriweather", ui-sans-serif, system-ui, sans-serif;
--font-body: "Source Sans Pro", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #000000 (~43%) · Surface #FFFFFF (~50%) · Text #F8F8F8 (~2%) · Muted Text #777777 (~4%) · Accent #0045FF (~1%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Centered Headline + Input
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Category Positioning Anchor
- Hero components: Interactive Hero Tool
- Spatial layout notes: Centered Headline + Input hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring centered headline + input 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.
