/* ⚠ NO FIXED ASPECT RATIO AND NO object-fit:cover. The stills are ~300 px tall with widths from 92 to
   302 in 144 distinct combinations — a 1/1 frame with cover would crop most of them. Each <img> carries
   its own real width/height from the manifest, so the browser reserves exactly the right box and nothing
   shifts on load. Rendered at natural size rather than stretched: upscaling a 92 px-wide source to a
   720 px column is blur, not presence. When there is no still the <figure> is not emitted at all. */
