+/// Mix of two Nextcloud surfaces:
+/// - User info comes from the OCS provisioning API
+///   (`/ocs/v2.php/cloud/users/{userId}`).
+/// - The own-avatar upload/delete uses the *core* AvatarController at
+///   `/avatar/` — the OCS provisioning route has no POST (it answers 405).
+///   This is the same controller the read path (`/avatar/{id}/{size}` in
+///   [UserAvatar]) already talks to. CSRF is bypassed because we use Basic
+///   Auth without a session cookie.

+/// Core AvatarController endpoint for the logged-in user (POST sets, DELETE
