+/// <summary>
+/// A drop zone which reports the paths of whatever was dropped on it, and nothing else.
+/// </summary>
+/// <remarks>
+/// Dropping is a native matter in AI Studio: the Tauri runtime reports real paths, which is why
+/// this zone can hand out folders just as well as files. What those paths mean is the consumer's
+/// business — this component reads no content and does not care whether a path leads to a file or
+/// to a folder.
