# Design Brief: Minimal Monochrome (with Editorial)

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

## Design Tokens

```css
:root {
  --background: #050505;
  --surface: #181818;
  --foreground: #f4f1ed;
  --muted-foreground: #888582;
  --accent: #bfc0c2;
  --radius: 16px;
  --font-heading: "Noto Serif JP", serif;
  --font-body: "Noto Serif JP", serif;
}
```

Color area ratio: Background #050505 (~79%) · Surface #181818 (~7%) · Text #F4F1ED (~7%) · Muted Text #888582 (~4%) · Accent #BFC0C2 (~3%). 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: Dark · Airy
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: 3D Render / Tactile Object
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Outcome & Speed Promise
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and user count, rating, or key metrics.
- Visual summary: Minimal Monochrome (Dark canvas, airy density) featuring split copy & visual layout and 3d render / tactile object 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.
