Local processing inputs

Local Worker: 10s startup, 1s processing. 32KiB per field, 1MiB complete result. Editing or clearing cancels work and stale output. Generated HTML/CSS is not mounted; remote image preview requires a separate action.

Preview and code

Edit fields and build a preview; complete code can be copied or downloaded.

Model and scope

Export iframe code with an always-present sandbox, accessible title and explicit capabilities. Scripts plus same-origin can defeat sandboxing for same-origin content; review that combination. The preview is a permission table; no iframe is mounted or URL loaded.
