# Design Brief: Minimal Monochrome (with Dark Developer)
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #222222;
--foreground: #34363b;
--muted-foreground: #626873;
--accent: #4938f5;
--radius: 8px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-mono: "Geist Mono", ui-monospace, monospace;
}
```
Color area ratio: Background #FFFFFF (~72%) · Surface #222222 (~17%) · Text #34363B (~6%) · Muted Text #626873 (~4%) · Accent #4938F5 (~1%). 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: Light · Balanced
- Border radius & elevation: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Video Demo, Code & Terminal
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with download app / install extension CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring headline over large product shot layout and code block / terminal / cli visuals.
## Avoid
- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color
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.
