     This media query ALSO fired at max-width 640px when first shipped, to save
     mobile bandwidth. That trigger was removed after measurement: `display: none`
     does NOT stop the download. Chromium requests the file with Range: bytes=0-
     and pulls all 1,850,735 bytes even when the element is hidden. Mobile was
     therefore paying full price for the video and being shown a still, so the
     still was pure loss. Mobile now gets the same loop as desktop.
     The <video> poster attribute remains the fallback for iOS Low Power Mode and
     any browser that refuses autoplay - that is handled by the element, not by CSS. */
