   - The button may be left empty: main.js then fills the icon, the label and the duration (from data-dur="48" or
     "0:48" on the figure, else from the file once it loads).
   - The figure has no width of its own: put it in a grid column or a block. The frame is always exactly 16:9 and
     the picture is never cropped (object-fit: contain).
   - poster= loads with the page. For a film far down a long page, data-poster= instead lets main.js set it near
     the viewport.
