# Design Brief: Minimal Monochrome (with Soft & Friendly)

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

## Design Tokens

```css
:root {
  --background: #f7f7f7;
  --surface: #ffffff;
  --foreground: #090909;
  --muted-foreground: #606060;
  --accent: #58cc00;
  --radius: 16px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F7F7F7 (~69%) · Surface #FFFFFF (~22%) · Text #090909 (~4%) · Muted Text #606060 (~4%) · Accent #58CC00 (~1%). 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: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Outcome & Speed Promise
- Hero components: Interactive Hero Tool
- Spatial layout notes: Centered Headline + CTA hero structure paired with direct input / instant try CTA and user count, rating, or key metrics.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring centered headline + cta 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.
