/* ==========================================================================
   Marco común de la documentación (21-10-2026): barra superior, encabezado,
   botones y pie, iguales a los de la portada (css/index.css). Lo cargan TODAS
   las páginas de docs/ (documentos, portadas de documentación, manuales y
   presentaciones), antes de su hoja de contenido; los temas los aplica
   temas_paginas.css (que se carga al final) sobre nav, .nav-logo, .doc-card…
   Marcado:
     <nav class="site-nav">
       <a class="nav-logo" href="…">Ruta<span>CC</span></a>
       <ul class="nav-links"><li><a href="…" aria-current="page">…</a></li>…</ul>
     </nav>
     <footer class="site-footer"><div class="footer-logo">…</div><div class="footer-copy">…</div></footer>
   Los manuales agregan en la barra el botón del menú (.menu-toggle) y el buscador (.search).
