# Design Brief: Minimal Monochrome (with Enterprise Clean)

Monochrome palette with a single accent color, hairline dividers, and generous whitespace.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f3f3f3;
  --foreground: #0a0f25;
  --muted-foreground: #6b7280;
  --accent: #526fe9;
  --radius: 4px;
  --font-heading: "SourceSansPro", ui-sans-serif, system-ui, sans-serif;
  --font-body: "SourceSansPro", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "monospace", ui-monospace, monospace;
}
```

Color area ratio: Background #FFFFFF (~74%) · Surface #F3F3F3 (~15%) · Text #0A0F25 (~6%) · Muted Text #6B7280 (~3%) · Accent #526FE9 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Start Free / Sign Up · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Code & Terminal
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring centered headline + cta layout and product ui screenshot / component 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.
