    // bypasses Rust's ownership and borrowing rules. This is done to dynamically clone a boxed
    // trait object, which doesn't support cloning through the standard `Clone` trait. The operations
    // within this block are carefully crafted to ensure memory safety manually, including proper
    // allocation and deallocation of heap memory for the clone.
