+/**
+ * The FileUpload component provides a drag-and-drop zone and a button for uploading files.
+ * Note: File state must be maintained outside this component. The component is stateless
+ * and will only trigger callbacks when files are selected, dropped, or deleted.
+ *
+ * @example
+ * ```jsx
+ * const [files, setFiles] = useState({});
+ *
+ * const handleFilesSelected = (fileList) => {
+ *   // Process files and update state
+ * };
+ *
+ * return (
+ *   <FileUpload
+ *     id="file-upload"
+ *     title="Upload files"
+ *     label="Choose files"
+ *     files={files}
+ *     onFilesSelected={handleFilesSelected}
