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

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

## Design Tokens

```css
:root {
  --background: #000000;
  --surface: #202020;
  --foreground: #f0f0ee;
  --muted-foreground: #929292;
  --accent: #bdedd9;
  --radius: 16px;
  --font-heading: "Windsor", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #000000 (~63%) · Surface #202020 (~10%) · Text #F0F0EE (~8%) · Muted Text #929292 (~7%) · Accent #BDEDD9 (~12%). 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: Left App Sidebar
- Theme & density: Dark · Dense
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up · Trust bar uses Live Generated Output Showcase
- Headline hook: Direct Action Command
- Hero components: Custom Illustration
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Dark canvas, dense density) featuring split copy & visual 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.
