+<?php
+// api/src/Serializer/MediaObjectNormalizer.php
+
+use App\Storage\StorageInterface;
+use ApiPlatform\GraphQl\Serializer\ItemNormalizer;
+
+final readonly class MediaObjectNormalizer

+        private NormalizerInterface $normalizer,
+        private StorageInterface $storage
+    ) {}
+    
+    // ...
+}
+
