/**
 * The single place in the app layer that knows which package renders the
 * editing surface. Everything else in the app interacts with the editor via
 * the `editorEngine` service slot (`EditorEngineContract`).
 *
 * Known exception to the engine-agnostic seam: the surface component itself
 * is engine-specific because it renders the engine's own overlay UI (slash
 * menu, link menu, table menu, ...). This module is therefore the per-engine
 * component switch (plans/011-wordgard-editor-w-migration.md).
