Full-width responsive contents for iframe embeds in help articles

Embedding third-party content (e.g. Arcade, Vimeo) into help articles can currently only paste a URL into the “Custom frame” block, which renders the iframe with fixed padding and visible white bars on the sides.

I’d like iframes to be able to span the full article content width and respect the provider’s embed snippet (including styling/aspect ratio).

This request is to:

• Allow full-width content, responsive iframes within article content (no side padding/white bars) - allow adjusting height

• Optionally support pasting full iframe HTML snippets (not just URLs) or provide controls for width/height/aspect ratio so embeds match the intended design from tools like Arcade and Vimeo, both in the editor and in the published article.
