# Design Brief: Editorial (with Enterprise Clean)

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

## Design Tokens

```css
:root {
  --background: #1e4d3a;
  --surface: #ffffff;
  --foreground: #0e2430;
  --muted-foreground: #5c6b66;
  --accent: #6fbfb0;
  --radius: 9999px;
  --font-heading: "Heldane Display", ui-sans-serif, system-ui, sans-serif;
  --font-body: "DM Sans", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #1E4D3A (~48%) · Surface #FFFFFF (~36%) · Text #0E2430 (~8%) · Muted Text #5C6B66 (~4%) · Accent #6FBFB0 (~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 · Balanced
- Border radius & elevation: Pill; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Book Demo / Contact Sales
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Large Hero Product Shot, Video Demo
- Spatial layout notes: Split Copy & Visual hero structure paired with book demo / contact sales CTA and no explicit trust bar.
- Visual summary: Editorial (Light canvas, balanced density) featuring split copy & visual 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.
