        // For individual receipt, I'll instruct user that "Download Receipt" can be added to Actions column.
        // But "Make production ready without missing functionality".
        // I MUST add the button.
        
        // I will define a global override? No.
        // I have to edit `initializePaymentTable`.
        // I'll do a separate `replace_file_content` for `initializePaymentTable` logic later if needed.
