# Design Brief: Retro & Nostalgic

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

## Design Tokens

```css
:root {
  --background: #000000;
  --surface: #ffffff;
  --foreground: #fafffa;
  --muted-foreground: #8c918d;
  --accent: #4fff69;
  --radius: 4px;
  --font-heading: "rumble", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Segoe UI Symbol", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #000000 (~77%) · Surface #FFFFFF (~10%) · Text #FAFFFA (~7%) · Muted Text #8C918D (~2%) · Accent #4FFF69 (~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: Dark · Airy
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Start Free / Sign Up
- Headline hook: Target Audience Callout
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Retro & Nostalgic (Dark canvas, airy density) featuring split copy & visual layout and pure typography & geometry visuals.

## 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.
