+// Live betting: who's to act, what it costs them, and where the money goes.
+//
+// This is bookkeeping, not a game — the dealer taps what the humans at the table
+// actually did, and the tool keeps the arithmetic straight. It deliberately never
+// blocks an action it thinks is "illegal"; a dealer overruling the maths is right
+// more often than the maths is.
+//
+// Money model: `player.committed` is what a seat has put in on the current street.
+// When a street closes it sweeps into `player.amountOverride`, which is the seat's
+// total for the hand — the same field the pot badge, the pot wizard, the standings
+// and the CSV already read. So the betting bar is a fast way to fill in a field
+// that already existed, and nothing downstream had to change.
