+/**

+ * live ProdCom. Serves the endpoints the module uses — channels, groups,
+ * transcript history and the SSE stream — and simulates live speech:
+ * entries appear in progress, grow word by word (same id, in-place update),
+ * then complete.
+ *
+ *   node tools/prodcom-mock.js [port]      (default 24480)
+ *
+ * Point the module's admin config at http://127.0.0.1:<port>. Kill and
+ * restart this process while tiles are open to watch them degrade and
+ * recover on their own.
