   source aspect ratio (320x206) rather than left to `auto`, so the header
   does not reflow when the image lands.

   The <picture> wrapper is what swaps the colour mark for the white one in
   dark mode, so it needs to behave as the flex child itself -- without this
   the wrapper collapses and the image loses its box. */
