+//
+// 设计要点：
+//   - 远程媒体的元数据完全不落库：每次请求实时向远程 Emby 拉取；
+//   - 条目 ID 用 embyremote~{accountID}~{remoteID} 伪装（见 emby_remote_ids.go），
+//     客户端拿伪装 ID 回来时按账号路由回远程；
+//   - 播放分流由账号级 proxy_play 配置决定：
+//     不代理（默认）= MediaSource 下发热门远程绝对 URL，播放字节完全不经过 MMTL；
+//     代理 = 下发 MMTL 本地 /Videos/{encoded} 端点，由 ProxyVideoStream 反向拉流。
+//
+// 配置复用 STRM 账号体系（StrmAccount.Provider = emby_remote），CRUD/加密/连通
+// 测试全部走既有 /admin/strm/accounts 接口，不需要新增数据表。
