# Design Brief: Minimal Monochrome
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #dce1e7;
--surface: #f8f8f8;
--foreground: #101112;
--muted-foreground: #818589;
--accent: #e84f94;
--radius: 9999px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #DCE1E7 (~57%) · Surface #F8F8F8 (~29%) · Text #101112 (~7%) · Muted Text #818589 (~5%) · Accent #E84F94 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure

- Theme & density: Light · Airy
- Border radius & elevation: Pill; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase

- Hero components: Centered Prompt / Input, Large Hero Product Shot
- Spatial layout notes: Centered Headline + Input hero structure paired with download app / install extension CTA and live generated output showcase.

## Avoid
- Multi-stop neon gradients
