# Design Brief: Editorial

Oversized serif headlines, narrow reading columns, and magazine-inspired grid layouts.

## Design Tokens

```css
:root {
  --background: #0e2348;
  --surface: #f6f1e8;
  --foreground: #ffffff;
  --muted-foreground: #c5cdd8;
  --accent: #6b6bd6;
  --radius: 8px;
  --font-heading: "Source Serif 4", serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #0E2348 (~58%) · Surface #F6F1E8 (~14%) · Text #FFFFFF (~16%) · Muted Text #C5CDD8 (~6%) · Accent #6B6BD6 (~6%). 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: Dark · Airy
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Target Audience Callout
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and user count, rating, or key metrics.
- Visual summary: Editorial (Dark canvas, airy density) featuring centered headline + cta layout and product ui screenshot / component 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.
