The package ships MessagePackAssumedFormattable(typeof(CultRecordRef<>)) as an
MSBuild AssemblyAttribute in buildTransitive, so generated resolvers defer the
ref to CultDocumentResolver. Geometry imports the targets and drops its three
per-member [MessagePackFormatter] workarounds. GeneratorConsumer is the
generator-on twin of ConsumerBuild.
