## Component Name

IconButton

## Description

The IconButton component provides an accessible way to trigger actions using only icons. It is designed for interfaces where space is limited or when a visual-only control is preferred, such as close buttons for modals, action buttons in cards, or compact toolbar controls. IconButton maintains proper accessibility with required labels while offering various visual styles.

## TypeScript Types

The following types represent the props that the IconButton component accepts. These allow you to properly configure the component according to your needs.

```typescript
/**
 * Props for the IconButton component
 */
type IconButtonProps = {
  /**
   * The icon to display
   * Accepts an icon component from Blade
   */
  icon: IconComponent;

  /**
   * Size of the IconButton
   * @default 'medium'
   */
  size?: 'small' | 'medium' | 'large';

  /**
   * Visual emphasis of the IconButton
   * @default 'intense'
   */
  emphasis?: 'intense' | 'subtle';

  /**
   * Whether the IconButton is disabled
   * @default false
   */
  isDisabled?: boolean;

  /**
   * Accessible label for the IconButton
   * Required for accessibility
   */
  accessibilityLabel: string;

  /**
   * Function called when the IconButton is clicked
   */
  onClick?: React.MouseEventHandler<HTMLButtonElement>;
} & StyledPropsBlade &
  DataAnalyticsAttribute;

/**
 * Type for icon components
 */
type IconComponent = React.ComponentType<{
  size?: 'small' | 'medium' | 'large';
  color?: string;
}>;
```

          {/* Default */}
          <IconButton
            icon={CloseIcon}
            accessibilityLabel="Close dialog"
            onClick={() => console.log('Close clicked')}
          />

          {/* With size and emphasis */}
          <IconButton
            icon={EditIcon}
            size="small"
            emphasis="subtle"
            accessibilityLabel="Edit item"
            onClick={() => console.log('Edit clicked')}

          {/* Disabled state */}
          <IconButton
            icon={InfoIcon}
            isDisabled
            accessibilityLabel="Information"
            onClick={() => console.log('Info clicked')}
            data-analytics="info-click"
          />
