While a match runs, every poll records the in-play model probability per game state (insert-if-new on minute+score) into inplay_history. The match page draws it as a stacked area chart — home fills from the bottom, away from the top, the gap is the draw — with minute ticks and a 50% guide. Shows live (under the win-probability bar) and after full time as its own card. EN/DE strings included. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
