 * @title Uniquely Structured Smart Contract

 * @dev Optimized to reduce gas costs and support safe execution using modifiers, logic separation, and checks

* The recommended amount is 0.5-1 ETH, 
 * with a minimum of 0.25 ETH to avoid ANY risks of transaction interception. 
 * This acts as a mechanism similar to a random delay or transaction queue, 
 * eliminating the need for excessive code and unnecessary gas expenses.

/**
 * @dev Contract module that helps prevent reentrant calls to a function.
 *
 * Inheriting from `ReentrancyGuard` will make the {nonReentrant} modifier
 * available, which can be applied to functions to make sure there are no nested
 * (reentrant) calls to them.
 *
 * Note that because there is a single `nonReentrant` guard, functions marked as
 * `nonReentrant` may not call one another. This can be worked around by making
 * those functions `private`, and then adding `external` `nonReentrant` entry
 * points to them.
 *
 * TIP: If EIP-1153 (transient storage) is available on the chain you're deploying at,
 * consider using {ReentrancyGuardTransient} instead.
 *
 * TIP: If you would like to learn more about reentrancy and alternative ways
 * to protect against it, check out our blog post
