แม่แบบ:การประกวดเพลงยูโรวิชัน

I appreciate your request, but I don't have access to the actual context of "Template:Eurovision Song Contest" that you're referring to. You've indicated it's a Wikimedia template, but without seeing its specific content, I cannot provide an accurate overview based solely on what it contains. To help you properly, could you share the template content or documentation?
