/* ═══════════════════════════════════════════════════════════════════════════
   FOOTER — one definition, loaded by every public page.

   This used to be two: home carried .foot-* here in site.css, /aprendizaje
   carried a near-identical .footer-* in landing.css, and the markup was
   copy-pasted into both documents. They had already drifted — different
   stacking behaviour on narrow screens, inline styles on one side — and a fix
   applied to one simply did not reach the other. The markup is now built once
   in site.js (see ctaForms/siteFooter there); these are its styles.

   Relies on --indigo-dark, --spark, --serif and --mono, which site.css and
   landing.css both define.
