Raffle is fair only if tokenRange is a power of 2.

Lines of code Vulnerability details Impact Based on the contract logic, the raffle works by sampling a value $ x \in \mathbbZ | 0 \leq x \lt 2^256 $ aka uint256 from a uniform distribution provided by Chainlink VRF, then applying modulo tokenRange, generating a new value $ y \in \mathbbZ | 0 \leq...
