# Design Brief: Minimal Monochrome (with Retro & Nostalgic)

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

## Design Tokens

```css
:root {
  --background: #f5f1e6;
  --surface: #f8f6ef;
  --foreground: #1a2118;
  --muted-foreground: #7a8174;
  --accent: #1e6b34;
  --radius: 16px;
  --font-heading: "Geist", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Geist", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Geist Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #F5F1E6 (~52%) · Surface #F8F6EF (~14%) · Text #1A2118 (~16%) · Muted Text #7A8174 (~8%) · Accent #1E6B34 (~10%). 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: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Hero components: Code & Terminal, Large Hero Product Shot
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring centered headline + cta layout and code block / terminal / cli 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.
