/* Shared site footer — structural, editorial, flows naturally at page bottom.
   Latimont mark + tagline on the left (with a quiet copyright line tucked
   underneath). Four columns of nav links on the right. No internal divider.

   Canonical HTML pattern (paste verbatim when rebuilding a page):

   <footer class="site-footer">
       <div class="footer-mark">
           <a href="/" class="wordmark">Latimont</a>
           <span class="positioning">Mortgage infrastructure.</span>
           <span class="footer-copy">&copy; 2026 Latimont. All rights reserved.</span>
       </div>
       <nav class="footer-nav">
           <div class="footer-col">
               <span class="footer-col-label">Product</span>
               <a href="https://criteria.latimont.com">Criteria</a>
