   Any inline content image (not a hero) should be wrapped in one of these
   instead of a raw <img>. Explicit aspect-ratio on the wrapper + object-fit:
   cover on the img means the image cannot be squashed/stretched no matter
   what the surrounding grid/flex row does to the wrapper's box. Relying on
   the HTML width/height attributes alone to imply aspect ratio is NOT
   sufficient once an image sits in a CSS Grid cell next to taller content —
   the browser can resolve width and height independently in that case and
   silently distort the image. Always use .media-frame for content images. */
