Randomizer

java.lang.Object

server.Randomizer

public class Randomizer extends Object

全伺服器共用的偽亂數工具類，封裝單一 Random 實例的靜態存取介面。

提供 nextInt、nextBoolean、nextDouble、nextFloat、 nextLong、nextBytes 等基本型別隨機方法，以及常用的範圍整數 rand(lbound, ubound) 與成功率判斷 isSuccess(rate)。

全域共享同一個 java.util.Random，不保證執行緒安全的統計獨立性，但對遊戲玩法而言已足夠；凡需要隨機數的 server.* 子系統（如 RandomRewards、戰鬥計算、掉落判定等）均依賴本類別。
