/* ==========================================================================
   ABI VISUALIZATION BLOG — styles specific to /blog/ and /en/blog/.
   Loaded AFTER /assets/css/style.css and /assets/css/responsive.css on
   every blog page — this file defines NO color/font tokens of its own on
   purpose. Every var(--...) below resolves against style.css's :root, so
   there is nothing here to fall out of sync with the site's palette or
   typography (see blog-src/build.js header comment for the full context).
   Header/footer/nav/mobile-menu styling and behavior also come from
   style.css + responsive.css + main.js — this file only adds the classes
   that are unique to blog pages.

/* ---------- Blog hero (index only) ----------
   Los estilos viven ahora en .hero-dark, en /assets/css/style.css, que
   esta pagina tambien carga. El indice del blog y el hub de
   /herramientas/ comparten hero, asi que comparten definicion: una sola.
   El marcado lleva las dos clases (blog-hero hero-dark); .blog-hero se
   conserva como gancho por si el blog necesita algo propio algun dia. */
