/* SITE FOOTER
   Same gradient hairline trick as the top navbar — a 1px gradient strip
   reads as a designed divider rather than a default border.

   Lives in its own file (not home.css) because the footer fragment is
   shared across every public page; styles need to load wherever the
   fragment does, which is why the head fragment links this directly. */

       eats the leftover space on short pages so the footer hugs the bottom;
       on tall pages it collapses to 0 and the footer follows the content. */
