   Site footer: brand block (logo, tagline, social links) beside four link
   columns, then a hairline-separated copyright bar. Logo reuses the header's
   .logo class verbatim; both it and .cta-button carry grid-column rules
   scoped to their original grid contexts (header bar / contact form), so
   they're reset here since the footer is itself a grid.
