Three scripts still reached upstream infrastructure, and running any of them
put its URLs back into the tree.
generate-catalog-pages emitted an absolute vendor CDN host into every catalog
page. The pages already checked in use root-relative /images/ paths, so a
regenerate reverted 306 of them; the base now matches what ships, and the docs
site serves the previews its own generator produces.
backfill-block-previews wrote a preview field into registry manifests from
that same CDN pattern. It is a one-shot migration nothing calls, and no
manifest carries the field it wrote. Gone.
upload-docs-images synced docs/images to an S3 bucket under an upstream AWS
profile. Its source directory does not exist, and the contributing guides
already say previews are served from the docs site and nothing is uploaded.
Gone, with the script entry and the comments that pointed at it.
