Post excerpt:
Thesys just open-sourced their generative UI rendering engine. Interesting timing given where Google a2ui and Vercel's json-render are headed.

# Design Brief: Minimal Monochrome

Monochrome palette with a single accent color, hairline dividers, and generous whitespace.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f4f4f5;
  --foreground: #111111;
  --muted-foreground: #6b6b6b;
  --accent: #111111;
  --radius: 9999px;
  --font-heading: "Geist", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Geist", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "Geist Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #FFFFFF (~62%) · Surface #F4F4F5 (~18%) · Text #111111 (~8%) · Muted Text #6B6B6B (~8%) · Accent #111111 (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Headline Over Large Product Shot
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Code & Terminal, Large Hero Product Shot
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with download app / install extension CTA and live generated output showcase.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring headline over large product shot layout and product ui screenshot / component visuals.

## Avoid

- Multi-stop neon gradients
- Heavy drop shadows
- More than one competing accent color

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.
