What engineers like:
Modern, open source package registry for JS/TS modules. ESM-only. Supports multiple package managers inc. npm, yarn, pnpm, Bun, Deno. Secure publishing workflows by default. Auto API doc generation and scoring to encourage best practices. Open source.
Trade-offs & limitations:
Requires a compatibility layer for npm. Forces you to use TypeScript and ESM, but it’s 2024 so this is also something we like!
Best suited for:
Developers of JS/TS modules should consider this tool

# Design Brief: Minimal Monochrome

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f8fafa;
  --foreground: #083344;
  --muted-foreground: #45494b;
  --accent: #f7df1e;
  --radius: 4px;
  --font-heading: "DM Sans", ui-sans-serif, system-ui, sans-serif;
  --font-body: "DM Sans", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~87%) · Surface #F8FAFA (~4%) · Text #083344 (~4%) · Muted Text #45494B (~3%) · Accent #F7DF1E (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + Input
- Navigation: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Category Positioning Anchor
- Hero components: Centered Prompt / Input
- Spatial layout notes: Centered Headline + Input hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Minimal Monochrome (Light canvas, airy density) featuring centered headline + input layout and interactive hero demo / tool 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.
