# Design Brief: Editorial (with Soft & Friendly)

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

## Design Tokens

```css
:root {
  --background: #e5f1e5;
  --surface: #ffffff;
  --foreground: #121212;
  --muted-foreground: #77777a;
  --accent: #e60a57;
  --radius: 8px;
  --font-heading: "Instrument Serif", serif;
  --font-body: "Inter Variable", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #E5F1E5 (~70%) · Surface #FFFFFF (~11%) · Text #121212 (~8%) · Muted Text #77777A (~7%) · Accent #E60A57 (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + Input
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Direct Input / Instant Try · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Outcome & Speed Promise
- Hero components: Centered Prompt / Input, Interactive Hero Tool, Metrics Strip
- Spatial layout notes: Centered Headline + Input hero structure paired with direct input / instant try CTA and user count, rating, or key metrics.
- Visual summary: Editorial (Light canvas, balanced density) featuring centered headline + input 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.
