# Design Brief: Editorial (with Soft & Friendly)

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f3f3f3;
  --foreground: #0f172a;
  --muted-foreground: #94a3b8;
  --accent: #4f1985;
  --radius: 9999px;
  --font-heading: "Instrument Serif", serif;
  --font-body: "Plus Jakarta Sans", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Space Grotesk", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~74%) · Surface #F3F3F3 (~15%) · Text #0F172A (~6%) · Muted Text #94A3B8 (~3%) · Accent #4F1985 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Avoid

- 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.
