# Design Brief: Minimal Monochrome (with Enterprise Clean)
Monochrome palette with a single accent color, hairline dividers, and generous whitespace.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #f8fafc;
--foreground: #27313f;
--muted-foreground: #7b8490;
--accent: #3788d8;
--radius: 8px;
--font-heading: "Segoe UI Symbol", ui-sans-serif, system-ui, sans-serif;
--font-body: "Segoe UI Symbol", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~80%) · Surface #F8FAFC (~7%) · Text #27313F (~6%) · Muted Text #7B8490 (~4%) · Accent #3788D8 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Headline Over Large Product Shot
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up · Trust bar uses Live Generated Output Showcase
- Headline hook: Outcome & Speed Promise
- Hero components: Large Hero Product Shot
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with start free / sign up CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring headline over large product shot 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.
