In-game NFL total projection: remaining possessions × adjusted points per drive, with a game-script layer (blowout/crunch/kneel-down/OT), weather and injury haircuts, an X-factor volatility warning, and a line-jump market-sentiment gauge built from your own line entries. Recomputes only when you press Update Over/Under; every press is logged and graded post-game.
