# Design Brief: Editorial (with Minimal Monochrome)
Oversized serif headlines, narrow reading columns, and magazine-inspired grid layouts.
## Design Tokens
```css
:root {
--background: #fbf7f0;
--surface: #ffffff;
--foreground: #1c1a17;
--muted-foreground: #6e675f;
--accent: #c47a2c;
--radius: 16px;
--font-heading: "Source Serif 4", serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FBF7F0 (~62%) · Surface #FFFFFF (~18%) · Text #1C1A17 (~10%) · Muted Text #6E675F (~6%) · Accent #C47A2C (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Large Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Download App / Install Extension
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Interactive Hero Tool
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Editorial (Light canvas, airy density) featuring centered headline + cta layout and pure typography & geometry visuals.
## Avoid
- Generic SaaS hero templates
- Cramped multi-column feature grids
- Neon cyber accents
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.
