  Responsive image with optional art direction: a separate mobile image (below 750px),
  each honouring its own focal point from the theme editor. Falls back to a placeholder.

  @param {image} [image] - Desktop image (also used on mobile when no mobile image is set)
  @param {image} [image_mobile] - Mobile image, below 750px
  @param {string} [class] - Class for the img element
  @param {string} [sizes] - sizes attribute for the desktop image (default 100vw)
  @param {boolean} [eager] - Load immediately with high fetch priority (use for the first sections on a page)
  @param {string} [placeholder] - placeholder_svg_tag name when no image is set (default 'lifestyle-1')

  @example
  {% render 'lib-image', image: section.settings.image, image_mobile: section.settings.image_mobile, class: 'lib-hero__img', sizes: '(min-width: 990px) 50vw, 100vw', eager: true %}
