# Design Brief: Editorial

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f2f2f2;
  --foreground: #000000;
  --muted-foreground: #333333;
  --accent: #009de0;
  --radius: 4px;
  --font-heading: "CMS", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Georgia", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~58%) · Surface #F2F2F2 (~28%) · Text #000000 (~6%) · Muted Text #333333 (~4%) · Accent #009DE0 (~4%). 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; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up
- Headline hook: Category Positioning Anchor
- Hero components: Custom Illustration
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Editorial (Light canvas, airy density) featuring split copy & visual layout and illustration / character art 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.
