Object Shapes

1. Create a Product interface with:
   • id: string, name: string, price: number
   • status: 'active' | 'inactive' | 'discontinued'
   • optional description?: string
2. Implement getProductSummary(product: Product): string that includes the name, price, and either the description or a clear no-description fallback (intended shape: name, price, then description text)
3. Create product (no description) and productWithDesc (with description: 'Has description') sample values
4. Export getProductSummary, product, and productWithDesc by name

Completion criteria

• Named exports: getProductSummary, product, productWithDesc
• Both samples use a valid status union member
• product.description is undefined; productWithDesc.description is 'Has description'
• Summary includes name and price, and uses the description when present (otherwise a no-description fallback) so the two samples produce different strings
