Optional ReadonlyformsValidate application/x-www-form-urlencoded and multipart/form-data
bodies with the same schema. The first-party service otherwise requires
application/json or application/*+json; an unsupported or absent type
answers 415 before any body read. Replacement services own their media-type
handling. Cookie-authenticated routes still need csrfMiddleware or
csrfFormMiddleware; pair opted-in forms with the latter. Read only for
the body target.
