/**
 * The wire frames of a live view (`GET /api/{table}:live`).
 *
 * A live view is one SSE stream that opens with a snapshot of a list query and
 * then delivers only what that view cares about. The server decides membership
 * and placement, so a client applies frames without knowing the filter or sort
 * rules, and a reconnect replays a fresh snapshot instead of a refetch.
 *
 * Types only: both the browser client and the server import this module.
