   CAAT Footer — Component
   AEM client library: caat/components/footer/clientlibs/css
   Depends on: tokens.css, button.css, icon-button.css, social-links.css

   The site footer: a newsletter signup + back-to-top band, four
   labelled link-navigation columns, and a brand / legal / language /
   social bottom row. Composes Social/Share Links. Spacing comes from
   the spacing scale.
