/* ==================================================================
   FAIR FORD PHARMACEUTICALS — SITE FOOTER
   footer.css · load LAST on every page that renders the site footer
   ------------------------------------------------------------------
   One shared design for the whole site. The markup already exists in
   two places — inline in public/index.html and in renderFooter() in
   js/common.js — and both use the same class names, so this single
   sheet drives them identically.

   It must load after style.css / about.css / contactus.css /
   product.css, each of which styled the old white footer.

   Not loaded on uphaar.html or nueva-vida.html: those are standalone
   campaign pages with their own footers and palettes.
