While I don't have browsing capabilities, I can still provide some general information and ask for specifics like the date.

I can provide a quick explanation about the "high-risk" classification in Spain, determined by the national anti-violence commission. Factors include rivalry, historical incidents, and the number of visiting fans—like the 2022 Frankfurt event.

I could offer a concise bullet point list and ask if the user wants more details, such as a timeline or safety tips for attending.
