// TestStartLivestreamInputBlobShapes is the regression test for the prod
// "parsing CID in legacy blob: invalid cid: cid too short" failures on
// place.stream.live.startLivestream. The JS app uploads its thumbnail with
// @atproto/api (getting that library's BlobRef class) and sends the record
// through the @atproto/lex client, whose lexStringify doesn't recognize the
// foreign BlobRef and serializes it field-by-field — producing a modern blob
// WITHOUT $type. That shape (and an explicit null thumb) must decode.
