The Storage::put() method accepts a path and content (string or resource) to create or overwrite a file. It returns a boolean indicating operation success. This method is ideal for storing dynamically generated content like CSV exports, JSON reports, or content downloaded via API. For form uploads with UploadedFile, putFile() or putFileAs() are more appropriate.
