Render previews of an existing ad

Renders an EXISTING ad per placement via Meta's `/{ad_id}/previews`. Each preview is an HTML `<iframe>` snippet embeddable directly. Unknown `formats` values return Meta's 400 verbatim.

Delete a creative

Deletes a creative from the library. Meta only allows deleting creatives not referenced by any ad — otherwise its 400 surfaces verbatim.

accountId*string

Zernio SocialAccount id (posting or ads variant); its platform decides where the campaign is created.
