/**
 * Lazy-loading wrapper for CaaSEventStream to prevent browser import errors.
 *
 * This module provides a browser-safe way to import CaaSEventStream.
 * The actual CaaSEventStream (which depends on better-sse) is only loaded
 * when getEventStreamHandler() is called, which should only happen on the server.
 *
 * Usage:
 * ```typescript
 * import { CaaSEventStream } from 'fsxa-api'
 *
 * // On server (Node.js):
 * const handler = CaaSEventStream.getEventStreamHandler(api)
 *
 * // In browser: CaaSEventStream exists but won't load better-sse unless called
 * ```
