/**
* This application creates a client-side data URI generator with the following features:
* - File upload through input and drag-and-drop
* - Automatic MIME type detection
* - Preview of the uploaded file (image, video, audio, or text)
* - Copy button to easily copy the generated data URI
*
* We'll use the FileReader API for file handling and data URI generation.
