   KRITEXA LABS — FOOTER CSS
   css/footer.css

   UI Refinement — Premium footer system

   Covers:
     - Global CTA section (.gcta)
     - Footer layout (.footer)
     - Newsletter card (.f-nl-block) — separate top card
     - Main footer card (.f-main-card) — ONE SINGLE OUTER CARD
         contains navigation grid, company panel, and bottom bar
     - Navigation area (.f-nav-area, .f-col, .f-col-links)
     - Company area (.f-company-area, .f-brand-logo, .f-brand-desc)
     - Social icons (.f-socials, .f-soc, per-platform hover colors)
     - Footer bottom bar (.f-bottom-bar) — INSIDE .f-main-card
     - Legal pending links (.f-link-pending)
     - Footer special link colors (.f-link-labs, .f-link-kai)
     - Responsive breakpoints
     - Reduced-motion overrides
     - Focus visible states

   Load order:
     global.css → utilities.css → header.css → footer.css → components.css

   CSS Architecture:
     - Uses design tokens from css/tokens.css (via global.css)
     - No arbitrary hard-coded values — references tokens where possible
