What Gracy demonstrated

Built a complete World Cup prediction game end to end: rendered the fixture board, implemented exact-result and result-only scoring, computed team strengths from real results, and used them in a bot predictor that responds to both teams. Also persisted and ranked the leaderboard across reloads, then deployed the finished game to a live HTTPS URL.
