Post excerpt:
I am very bad at remembering shell command options, so I often prefer to use scripts. But shell commands are nice because 1) I can just press ↑ to iterate 2) scripts need a name and location, which is hard to think of 3) they make it so easy to interact with files! bunsh aims to bridge the cap.

# Design Brief: Minimal Monochrome

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

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f3f3f3;
  --foreground: #111111;
  --muted-foreground: #8a8a8a;
  --accent: #ff2d87;
  --radius: 4px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #FFFFFF (~58%) · Surface #F3F3F3 (~12%) · Text #111111 (~14%) · Muted Text #8A8A8A (~8%) · Accent #FF2D87 (~8%). 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: Light · Balanced
- Border radius & elevation: Small Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Download App / Install Extension · Trust bar uses Customer / Press Logo Strip
- Headline hook: Outcome & Speed Promise
- Hero components: Code & Terminal, Metrics Strip, Customer Logo Wall
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and customer / press logo strip.
- Visual summary: Minimal Monochrome (Light canvas, balanced density) featuring split copy & visual layout and code block / terminal / cli 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.
