/**
 * Used to embed sound content into documents via the native `<audio>` element. It may contain
 * one or more audio sources, represented using the `src` attribute or the `<source>` element: the
 * browser will choose the most suitable one.
 *
 * 💡 This element contains the exact same interface as the `<audio>` element. It redispatches
 * all the native events if needed, but prefer the `vds-*` variants (eg: `vds-play`) as they
 * iron out any browser issues.
 *
 * @tagname vds-audio
 * @slot Used to pass in `<source>`/`<track>` elements to the underlying HTML5 media player.
 * @csspart media - The audio element (`<audio>`).
 * @csspart audio - Alias for `media` part.
 * @example
 * ```html
 * <vds-audio src="/media/audio.mp3">
 *   <!-- Additional media resources here. -->
 * </vds-audio>
 * ```
 * @example
 * ```html
 * <vds-audio>
 *   <source src="/media/audio.mp3" type="audio/mp3" />
 * </vds-audio>
