# Design Brief: Minimal Monochrome

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f5f5f5;
  --foreground: #111111;
  --muted-foreground: #555555;
  --accent: #ff8888;
  --radius: 4px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Courier New", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~69%) · Surface #F5F5F5 (~4%) · Text #111111 (~5%) · Muted Text #555555 (~3%) · Accent #FF8888 (~19%). 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: Minimal Logo + Action
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Download App / Install Extension · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Direct Action Command
- Hero components: Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and stacked avatars & testimonials.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring centered headline + cta layout and illustration / character art 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.
