The SEO-Friendly URL Slug Generator

Act as a technical SEO specialist. Help me create a clean, user- and SEO-friendly URL path for the product page.

• Product Name: [e.g., "UltraLight 360° Rolling Carry-On Luggage"]
• Primary Keyword: [e.g., "carry on luggage"]

Task: Generate 3 options for an optimal URL slug (the part after the domain.com/). They should be 3-5 words, lowercase, use hyphens to separate words, and contain the primary keyword. Avoid stop words like 'and', 'the', 'a'.
