# Design Brief: Minimal Monochrome (with Enterprise Clean)

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

## Design Tokens

```css
:root {
  --background: #f8f9fc;
  --surface: #ffffff;
  --foreground: #38383a;
  --muted-foreground: #737680;
  --accent: #704ff2;
  --radius: 16px;
  --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 #F8F9FC (~78%) · Surface #FFFFFF (~8%) · Text #38383A (~8%) · Muted Text #737680 (~4%) · Accent #704FF2 (~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: Light · Airy
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Start Free / Sign Up
- Headline hook: Category Positioning Anchor
- Hero components: Interactive Hero Tool, Code & Terminal
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring split copy & visual layout and interactive hero demo / tool 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.
