# Design Brief: Editorial (with Minimal Monochrome)
Oversized serif headlines, narrow reading columns, and magazine-inspired grid layouts.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #f3f3f3;
--foreground: #000000;
--muted-foreground: #1e2934;
--accent: #0288d1;
--radius: 4px;
--font-heading: "webfont light", ui-sans-serif, system-ui, sans-serif;
--font-body: "Helvetica", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~73%) · Surface #F3F3F3 (~15%) · Text #000000 (~6%) · Muted Text #1E2934 (~4%) · Accent #0288D1 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Download App / Install Extension
- Headline hook: Category Positioning Anchor
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: Editorial (Light canvas, airy density) featuring split copy & visual 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.
