+ * `GET /api/avatar/v3/saved`.
+ *
+ * One row per (account, slot). The outfit itself is stored as the opaque JSON payload
+ * the client posted: we never query inside it, and its fields (OutfitSelectionsV2,
+ * FaceFeatures, …) are themselves JSON-in-a-string produced by the client's own
+ * serializer. Round-tripping it verbatim is both the simplest and the safest thing —
+ * re-encoding risks changing a payload the client has to parse back.
