//! Music source implementation for Radio Paradise

//! This module implements the [`pmosource::MusicSource`] trait for Radio Paradise,
//! providing access to the service's default image and identification information.

/// This struct implements the [`MusicSource`] trait to provide
/// standardized access to Radio Paradise's identification and branding.

/// # Examples

/// ```
/// use pmoparadise::RadioParadiseSource;
/// use pmosource::MusicSource;
///
/// let source = RadioParadiseSource;

/// // Get default image as WebP bytes
