   A missing file must draw nothing over the placeholder. The <img> box is 3x the frame height with
   object-fit: contain + object-position: top, so a real shot (frame aspect) still fills the frame, while WebKit's
   centred broken-image icon lands below the clipped frame. A 2px overscan clips WebKit's broken border. In
   Chromium/Firefox img::before/::after (rendered only for a broken image) repaint the placeholder. */
