一款 Fabric 伺服器模組，讓管理員可動態建立、管理「禮包碼」，玩家輸入後可領取自訂物品、訊息，並自動執行伺服器指令。支援完整郵件系統，方便玩家互相寄送信件與物品。

Features Overview

• Dynamic Redeem Code Management: Create, delete, list, and query redeem codes on the fly.
• Custom Rewards: Define custom item stacks and text messages.
• Advanced Editing: Adjust redeem code properties in real time, including items, messages, claim limits, expiration, and single/multiple-use rules.

• MIT License: Open source — freely modify and distribute.
