Considering VAR upgrades

I’ll be careful about factual accuracy since the prompt is a bit ambiguous. Options might include drafting an article or a Q&A format with concise bullet points. I should avoid making country-specific claims unless I know for sure. With the mention of “多国将全面升级 VAR 系统,” I’ll ask for more details or the source. Let's suggest a structure!Planning a response

I also want to mention impacts like potentially reducing offside delays and improving consistency while noting costs and privacy concerns. If they want an article, I’ll propose a 300-word news brief template with bullet points while keeping it concise. Let's draft that!
