- attach.PublicURL and (*File).URL build Winter File::getPath() URLs; the
thumbnailer decodes webp via golang.org/x/image v0.46.0 and checks the
image size from the header before decoding
- tide requests carry multipart parts (files beside the fixture pinned by
sha256) encoded with the fixed MultipartBoundary, so PHP and Go receive
byte-identical bodies
- tide masks the random partition, disk name and file id of url/thumb_url
upload URLs while still diffing prefix, size, mode and extension, and
NormalizePublications masks Carbon dates in the published album
