Clarifying user needs

I see that the user provided a Chinese sentence about the 2026 FIFA World Cup expansion to 48 teams, mentioning changes in group stages and knockout complexity. They didn't ask a direct question, so they might be looking for an article or analysis. I should clarify what they'd like, such as analysis, schedule format, predictions, or fixture generation. I also need to mention the adjustment in the 2026 format regarding group configurations.Explaining the 2026 World Cup format

As of 2023, the 2026 World Cup format features 12 groups of 4 teams, leading to a total of 104 matches, with 72 matches in the group stage. There will be a ranking system for third-placed teams based on points, goal difference, and other criteria. The knockout round will get more complex, with pairings depending on which third-placed teams qualify. FIFA will likely define bracket pairings without a draw, and they may have published bracket seeding and path tables.Recapping the 2026 World Cup format

The 2026 World Cup will have 12 groups (A–L) with the top 2 teams from each group advancing, plus the top 8 third-placed teams, making a total of 32 teams. There won't be extra time in the group stage, just normal tiebreakers. The tournament spans about 39-40 days, starting June 11 and ending July 19, with 104 matches overall. The host countries will be the US, Canada, and Mexico, using 16 venues. I could also create a small Python module to compute standings and generate bracket scenarios.
