# Design Brief: Minimal Monochrome

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f5f6f8;
  --foreground: #171c28;
  --muted-foreground: #858a93;
  --accent: #1b2230;
  --radius: 8px;
  --font-heading: "系统中文无衬线", ui-sans-serif, system-ui, sans-serif;
  --font-body: "系统中文无衬线", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~78%) · Surface #F5F6F8 (~4%) · Text #171C28 (~9%) · Muted Text #858A93 (~4%) · Accent #1B2230 (~5%). 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 · Airy
- Border radius & elevation: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Direct Checkout / View Pricing · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Pain Relief & Replacement
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Centered Headline + CTA hero structure paired with direct checkout / view pricing CTA and user count, rating, or key metrics.
- Visual summary: Minimal Monochrome (Light canvas, airy 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.
