- Not exactly a mind blowing tool — but I use tools like this all the time, and none of them (as far as I can tell) have output that is as minimal as it could be. Maybe someone will find it useful. - only encodes necessary characters - changes attribute quotes to single quotes - lowercases percent-encoding hex pairs - swaps hex colors to their shorter named eq

# Design Brief: Retro & Nostalgic
Pixel typography, classic OS window chrome, or warm vintage print palettes.
## Design Tokens
```css
:root {
--background: #e9e0d9;
--surface: #e2d6cc;
--foreground: #0b0b0b;
--muted-foreground: #ae9f90;
--accent: #087ea1;
--radius: 0px;
--font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
--font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
--font-mono: "Courier New", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #E9E0D9 (~48%) · Surface #E2D6CC (~44%) · Text #0B0B0B (~4%) · Muted Text #AE9F90 (~3%) · Accent #087EA1 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Editorial Serif Headline
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Sharp; use elevation shadows to separate layers
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Pain Relief & Replacement
- Spatial layout notes: Editorial Serif Headline hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Retro & Nostalgic (Light canvas, balanced density) featuring editorial serif headline 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.
