+/**
+ * Regression tests for the WhatsApp bridge send queue (#33360).
+ *
+ * The bridge must serialise all sock.sendMessage() calls through a
+ * promise-based queue so that concurrent HTTP /send requests never
+ * produce overlapping Baileys socket writes.  Overlapping writes are
+ * the confirmed root cause of cross-chat contamination.
+ *
+ * These tests exercise the queue itself — they do NOT require a live
+ * WhatsApp socket.
