🚧 Embed Shape

An embed shape would host external web content (a video, a map, a live document) inside an <iframe> placed on the canvas.

Planned — not yet available.

The closest built-in types in @oh-just-another/scene are ImageElement (raster content, optionally backed by the binary-file registry) and TemplateElement (a host-defined component identified by templateId with arbitrary data). A TemplateElement is the recommended extension point for rendering custom or third-party content until a dedicated embed type exists.
