A reusable React component that displays a horizontal row of icon placeholders with configurable sizing and styling.

## Key Components

- **IconsBlock** - Main component that renders a flex container with icon placeholders
- **IconsBlockProps** - Interface extending `HTMLAttributes<HTMLDivElement>` with:
  - `icons?: string[]` - Array of icon identifiers (currently used for count/mapping)
  - `size?: 'sm' | 'md' | 'lg'` - Controls icon dimensions (4x4, 6x6, 8x8 pixels)
- **sizeClasses** - Object mapping size variants to Tailwind CSS classes

## Usage Example

```typescript
import { IconsBlock } from "./components/icons-block"

// Basic usage with medium-sized icons
<IconsBlock icons={["user", "settings", "bell"]} />

// Large icons with custom styling
<IconsBlock 
  icons={["github", "twitter", "linkedin"]} 
  size="lg"
  className="bg-gray-100 p-4 rounded-lg"
/>

// Small icons for compact layouts
<IconsBlock 
  icons={["edit", "delete"]} 
  size="sm"
  className="ml-auto"
/>
```

The component currently renders placeholder divs with `bg-primary/20` styling. Each icon gets a rounded background with secondary color and proper spacing. The `icons` array length determines how many placeholders are rendered, making it easy to integrate with actual icon libraries by replacing the placeholder div with real icon components.
