#![forbid(unsafe_code)]
//! Thin facade for the `use-media` workspace.
//!
//! The crate reexports the focused media crates directly so consumers can opt
//! into one dependency while still using the smaller APIs.
//!
//! # Examples
//!
//! ```rust
//! use use_media::*;
//!
//! let dimensions = Dimensions::new(1920, 1080).unwrap();
//! let aspect = AspectRatio::new(1920, 1080).unwrap();
//! let mime = parse_media_type("video/mp4").unwrap();
//!
//! assert_eq!(classify_resolution(1920, 1080).unwrap(), ResolutionClass::FullHd);
//! assert_eq!(aspect.label(), "16:9");
//! assert_eq!(mime.kind(), MediaKind::Video);
//! assert_eq!(dimensions.area(), 2_073_600);
//! ```
