14- * This example demonstrates the simplest possible interactive WebSocket
15- * client built with the Vix.cpp WebSocket module. It connects to a server,
16- * listens for typed JSON messages, prints structured chat output, and allows
17- * the user to send messages through a basic terminal prompt.

19- * Core Features Demonstrated
20- * ---------------------------
21- * 1. Client Creation:
22- * The example creates a WebSocket client targeting localhost:9090 and
23- * automatically manages connection state through Vix.cpp abstractions.

25- * 2. Typed JSON Protocol Handling:
26- * Incoming frames are parsed using JsonMessage and routed based on their
27- * "type":
28- * • chat.system - server/system events
29- * • chat.message - regular chat messages
30- * • fallback - prints raw JSON

33- * The client will automatically attempt to reconnect every 3 seconds
34- * if the connection is lost.

37- * A periodic ping is enabled to keep NAT/proxy connections alive.

43- * Intended Usage
44- * --------------
45- * This minimal client is ideal for:
46- * - Testing or debugging a Vix.cpp WebSocket server
47- * - Learning how to work with the JSON protocol
48- * - Building simple chat tools or monitoring utilities
49- * - Demonstrating the basics of WebSocket event handling in C++

51- * How to Run
52- * ----------
53- * 1. Start a Vix WebSocket server (see simple_server.cpp).
54- * 2. Build this example:
55- * cmake -S . -B build && cmake --build build -j
56- * 3. Run the client:
57- * ./build/examples/simple/simple_client
58- * 4. Type messages interactively, or use "/quit" to exit.
