/* ============================================================
   Synerxgy — hoja de estilos de las páginas estáticas
   (blog/, glosario/, buscar/)

   Estas páginas no pasan por React, pero tienen que verse igual que las
   públicas de la SPA (/about, /producto/*, /legal/*):
   - tokens = los de client/src/index.css (claro y oscuro, mismos valores);
   - cabecera y pie = copia de PublicLayout.tsx y GlobalFooter.tsx;
   - artículo = tipografía de MarketingPageShell.tsx;
   - hero y CTA = los de la landing (hero-bg, hero-gradient, btn-glow).

   Si cambian los tokens o la cabecera/pie de la app, cambia esto también.
   Tema: oscuro por defecto (igual que la app). /seo-assets/theme.js pone
   class="light" en <html> si el usuario eligió claro en la app.
