/**
 * # Realtime API JavaScript client
 *
 * The public API of the client. Consumers configure the client with
 * {@link permutive}, then {@link Permutive.openSession} opens a session and
 * resolves the {@link Session} it runs: declare the
 * {@link Context}, run imperative commands ({@link Session.identify},
 * {@link Session.track}), and
 * observe the replicated {@link SessionState}. Read cohorts out of that state
 * with {@link getCohorts} / {@link getActivation}.
 *
 * The {@link Transport} is an internal detail, but it is exported so a custom
 * one can be injected in place of the default {@link WebSocketTransport} —
 * e.g. {@link Http1Transport}, the serial-POST fallback for environments
 * that cannot hold a WebSocket. Only the transport you import is bundled.
 *
 * ## Getting Started
 *
 * Imperative calls resolve a {@link https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise | PromiseLike}:
 * a modern client can `await` them; an ES5 client with no `Promise` runtime
 * drives the same value with `.then(onFulfilled, onRejected)`.
 *
 * ```ts
 * permutive({ apiKey: 'pk_…' })
 *   .openSession()
 *   .then(
 *     session => {
 *       // An imperative command: each method resolves with its typed result.
 *       session
 *         .identify({ identities: [{ tag: 'email', id: 'a@b.c' }] })
 *         .then(result => console.log(result.output.user_id))
 *
 *       // Observe every applied fold of session-state.
 *       session.onStateChange(change => {
 *         console.log(getCohorts(change.current))
 *       })
 *     },
 *     error => console.error(error),
 *   )
 * ```
