## Files

### `c-marker-2.tsx`

```tsx
import type { ReactNode } from "react"

import {
  Marker,
  MarkerContent,
  MarkerIcon,
} from "@/components/ui/marker"
import { IconPlaceholder } from "@/app/(create)/components/icon-placeholder"

type ToolCall = {
  id: string
  label: string
  icon: ReactNode
}

// Each row carries a finished icon element rather than an icon name, because
// every library prop below has to stay a literal string for the registry
// installer to rewrite it. A name looked up from the row would not survive.
//
// None of them takes a size class either. A marker sizes a plain svg child for
// you, and that size is smaller in the compact styles, so a fixed size here
// pins one icon to one style's scale and looks wrong in the rest.
