/* Every image box below states BOTH dimensions, and leaves the artwork's own
   proportions to object-fit. This is deliberate: SVG intrinsic sizing is not
   reliable across engines. The article banner, for one, declares width="100%"
   and no height, so it carries no intrinsic dimensions at all — only a viewBox
   ratio. Firefox infers a size from that; WebKit does not, and the image blows
   up. Relying on `width: auto` or `height: auto` for an SVG invites the same
   class of bug, so nothing here does.

   The triskele is a single black path, so it also has to be inverted in dark
   mode or it disappears against the background. */
