//! Drop zone widget for drag-and-drop targets
//!
//! A configurable drop target area that accepts dragged items.
//!
//! # Example
//!
//! ```rust,ignore
//! use revue::widget::DropZone;
//!
//! DropZone::new("Drop files here")
//!     .accepts(&["file", "text"])
//!     .on_drop(|data| {
//!         println!("Dropped: {:?}", data);
//!         true
//!     })
//! ```
