Images Ad (static-ads) now compiles brief at bind: labeled Headline / Body /
CTA pin the type overlay; generate stays scene-only. A URL-only brief (no
markdown headings) scrapes the page first, same as chat Send.
The generate leaf is Gemini Image (gemini-3-pro-image at 2K). Pillow still
burns letter-perfect copy on Finalize. You can swap the generate node on the
graph if you want Seedream instead.
