Code execution

Use the Lucide `SquareTerminal` icon for "Code execution" in this project's interface.

Why this one: Code run in a sandbox, with its output

## Install

```bash
npm install lucide-react
```

## Use it

```tsx
import { SquareTerminal } from "lucide-react";

<SquareTerminal size={48} strokeWidth={2} />
```

## Keep these

- `size={48}` and `strokeWidth={2}` — the weight that sits correctly beside body text at this size. A default stroke of 2 at small sizes reads heavy next to text.
- No colour class: the icon inherits `currentColor` from its container, so it follows the surrounding text in both light and dark themes. Do not hardcode a hex value.
- Give it an accessible name when it stands alone (`aria-label`), or `aria-hidden` when it sits next to a text label that already says the same thing.

Used for this concept in: Code Execution. Use the same glyph across all of them — an interface that draws one concept two ways teaches the reader nothing.

Follows the size, stroke and colour above — adjust them and the prompt changes with it.
