# 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: #f5f5f5;
--foreground: #1b1b1b;
--muted-foreground: #707070;
--accent: #000000;
--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 #FFFFFF (~80%) · Surface #F5F5F5 (~7%) · Text #1B1B1B (~6%) · Muted Text #707070 (~4%) · Accent #000000 (~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: Left App Sidebar
- Theme & density: Light · Balanced
- Border radius & elevation: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Customer Logo Wall
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with start free / sign up CTA and customer / press logo strip.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring headline over large product shot layout and photography / live video 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.
