Functional Requirements

• Math: fee = amount * 1%.
• Accounting: net_prize = amount - fee.

Suggested Implementation

// IN FUNCTION: distribute_prize

// 1. Load 'fee_bps' from storage.
// 2. Calculate 'fee_amount'.
// 3. Transfer 'net_prize' to Winner.
// 4. Add 'fee_amount' to a 'CollectedFees' storage counter (do not transfer yet).
