type EventStructs = { [key: string]: AnyStruct };
An event with no event: field is named message. An event whose name has no own entry uses the default struct; with neither, the event is skipped and onInvalidEvent is called. Declare the event name __proto__ with a computed own key.
A string event struct keeps the raw data text. Every other kind is JSON text: JSON.parse, then the struct. A bare struct.literal therefore needs JSON text, not an unquoted token.
Reconnect lives on the client (withSSEReconnect). SSE jitter is a 0-1 multiplicative factor, same as WebSocket.
