Case contract

Profit boost promotion. Normal profit = stake * (price - 1). The boost increases the profit by boost_pct percent, but the extra winnings over the normal profit are capped at max_extra_cents. The displayed boosted price is 1 + (price - 1) * (1 + boost/100) rounded half up to two decimals (display only). Return [displayed price, potential return = stake + floor(normal profit + extra)].

Why this case matters

Promotional boosts must be applied to profit, not stake, and respect maximum extra winnings.
