# Design Brief: Retro & Nostalgic (with Editorial)

Pixel typography, classic OS window chrome, or warm vintage print palettes.

## Design Tokens

```css
:root {
  --background: #f4f1ed;
  --surface: #d3d0cb;
  --foreground: #201e1e;
  --muted-foreground: #777575;
  --accent: #a92f35;
  --radius: 4px;
  --font-heading: "Avenir", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Avenir", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Courier New", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F4F1ED (~72%) · Surface #D3D0CB (~8%) · Text #201E1E (~8%) · Muted Text #777575 (~4%) · Accent #A92F35 (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Avoid

- Generic modern corporate gradients
- Inconsistent mixing of modern flat UI and retro chrome

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.
