name: Appsmith embeddable and client-side components
note: Appsmith ships no JavaScript embed SDK. Embedding is done with a plain HTML iframe pointed at an app-specific
  Embed URL, with cross-origin control handled through window.postMessage. The one first-party npm distribution is
  the design system that powers the Appsmith editor itself, not an embedding library.
