A live, interactive prediction bracket for the 2026 FIFA World Cup. Visitors work through every round of 32 knockout matchup, pick a winner, and watch the bracket auto-advance all the way to the final.

Each matchup shows a win-probability split per team, an "Auto-fill" option to simulate a full bracket instantly, and Undo/Reset controls for replaying different outcomes. Picks persist in the visitor's own browser via localStorage, and a results panel tracks completion across all 31 matches.
