Client-triggered event. The `event` name must start with `client-`,
and the `channel` must be a private (`private-*`) or presence
(`presence-*`) channel (encrypted/cache variants of these prefixes
included). The server forwards the event to other subscribers but
does not echo it back to the sender. Rate limited; exceeding the
limit yields a `pusher:error` with code 4301.
Client-published event on a private or presence channel. Event name must start with `client-`.

About AsyncAPI
The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.
