+// Package service — 内置 dandanplay 应用凭据（签名认证回退用）。
+//
+// 弹弹play 开放 API（https://doc.dandanplay.com/open/）要求所有请求
+// 携带应用认证。官方推荐客户端应用使用「签名验证模式」：
+//
+// 请求头 X-AppId + X-Timestamp + X-Signature
+// X-Signature = base64(sha256(AppId + Timestamp + Path + AppSecret))
+//
+// Timestamp 为 UTC 秒级 Unix 时间戳，Path 为不含域名/查询参数的请求路径。
+// 该模式里 AppSecret 只存在于服务端本地，网络上传输的只有绑定
+// 时间戳与路径的签名，无法重放到其它请求上——这是「隐藏密钥」真正
+// 有效的部分。
+//
+// 为了让用户开箱即用，这里内置了一组项目自用凭据作为回退（在
+// DevCenter 申请）。管理员可在「弹幕」设置页填写自己的 AppId /
+// AppSecret 覆盖内置凭据。
+//
+// 混淆说明（重要）：开源项目无法真正隐藏随二进制分发的密钥，XOR
+// 混淆只能挡住直接扫源码/复制常量这种程度的提取，挡不住反编译内存
+// 取证。因此内置凭据只作为回退，不建议过度依赖它承载大流量。
