Computed server-side by the poll-snapshot lambda. Amounts are
string-encoded decimal cents-safe (e.g. "12.50", "-5.00")
— Tiltify's convention — so consumers should never parseFloat
blindly if they care about precision.
Semantics:
Increase — option amount went up, delta is positive.
New option — option appeared since prior snapshot, delta is the
full new amount (positive).
Removed option — option vanished, delta is the full prior amount
negated (negative). The optionID still refers to the removed
option so consumers can fade it out.
