+"""演示：服务器交易时段信息。
+
+通过 MacClient 的 get_server_info() 获取当前服务器的交易日期和交易时段配置。
+
+ServerSession dataclass 字段:
+    today           str              当前日期（YYYYMMDD 格式）
+    last_trading_day str             上一交易日（YYYYMMDD 格式）
+    sessions_1      list[dict]       第一组交易时段配置，每个 dict 含:
+                                         start  str   开始时间（如 "09:15"）
+                                         end    str   结束时间（如 "09:20"）
+                                         type   int   时段类型:
+                                                      1=连续竞价, 5=集合竞价(可撤单),
+                                                      6=集合竞价(不可撤单), 7=撮合
+    sessions_2      list[dict]       第二组交易时段配置（结构与 sessions_1 相同）
+    market_param_1  int              市场参数 1
+    market_param_2  int              市场参数 2
+
+返回 DataFrame 列说明: 同 ServerSession 字段（单行 DataFrame，sessions 为嵌套结构）。
