# Design Brief: Editorial (with Enterprise Clean)

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

## Design Tokens

```css
:root {
  --background: #f3f5f7;
  --surface: #ffffff;
  --foreground: #161616;
  --muted-foreground: #6e7380;
  --accent: #245bff;
  --radius: 16px;
  --font-heading: "Source Serif 4", serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F3F5F7 (~36%) · Surface #FFFFFF (~40%) · Text #161616 (~8%) · Muted Text #6E7380 (~6%) · Accent #245BFF (~10%). 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: Start Free / Sign Up · Trust bar uses Customer / Press Logo Strip
- Headline hook: Category Positioning Anchor
- Hero components: Customer Logo Wall
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and customer / press logo strip.
- 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.
