# Design Brief: Minimal Monochrome

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #fffdf0;
  --foreground: #242424;
  --muted-foreground: #88825c;
  --accent: #56340f;
  --radius: 4px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Courier New", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~83%) · Surface #FFFDF0 (~5%) · Text #242424 (~6%) · Muted Text #88825C (~4%) · Accent #56340F (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Full-Bleed Canvas / Video / 3D
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Interactive Hero Tool, Code & Terminal, Large Hero Product Shot
- Spatial layout notes: Full-Bleed Canvas / Video / 3D hero structure paired with direct input / instant try CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring full-bleed canvas / video / 3d layout and interactive hero demo / tool 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.
