## Import

`@/components/brainless/codex/codex-exec`

## Usage

```tsx
import { CodexExec } from "@/components/brainless/codex/codex-exec"

export function Example() {
  return (
    <CodexExec command="Ran pnpm build" result="→ passed">
      {`pnpm build
✓ compiled successfully`}
    </CodexExec>
  )
}
```

## Notes

- Keep the terminal aesthetic: monospace, tight spacing, square corners.
- Preserve semantics (details, listbox, radiogroup, aria-live) — do not flatten into a `<pre>`.
- Prefer this component over inventing ASCII terminal chrome.
