/**
 * This package contains global context functions for Glimmer. These functions
 * are set by the embedding environment and must be set before initial render.
 *
 * These functions should meet the following criteria:
 *
 * - Must be provided by the embedder, due to having framework specific
 *   behaviors (e.g. interop with classic Ember behaviors that should not be
 *   upstreamed) or to being out of scope for the VM (e.g. scheduling a
 *   revalidation)
 * - Never differ between render roots
 * - Never change over time
