/**
 * This is a smart component that automatically detects
 * the most common file types such as image, audio, video, and text,
 * and properly displays them in the browser.
 * The component is also capable to render the most common office files.
 *
 * :::note
 * Image files will always be contained in their containers, which means
 * they automatically increase or decrease in size to fill their containing box
 * whilst preserving their aspect-ratio.
 *
 * Text and PDF files will also always respect the width and height of the
 * container in which the `limel-file-viewer` is loaded.
 * :::
 *
 * For some file types such as text and images, the component will display a
 * download button and a button to open the file in a new browser tab.
 * This will allow users to preview the file in a fullscreen mode with the
 * browser and take advantage of for example native zooming and panning
 * functionalities.
