   CHANGELOG
   v1.6c 2026-03-15  Fix breadcrumb en single posts ZDU: agrega
                     body.single-post.category-zero-day-unit
                     (el PHP snippet ID 46887 solo aplica en
                     archive/hub, no en posts individuales).
   v1.6b 2026-03-15  Componentes narrativos faltantes: añadidos
                     .zdu-figure (cursor zoom-in + hover),
                     .zdu-sep, .zdu-villain-msg, .zdu-lightbox
                     completo (overlay + img + close + caption).
                     Eliminado bloque .zdu-family-nav duplicado
                     (secciones breadcrumb+nav repetidas x2).
                     Breadcrumb Yoast/Astra suppression intacto.
   v1.5b 2026-03-14  Fix margen H2 en entradas ZDU: Astra aplica
                     margin-top:42px a H2 por defecto; la regla
                     .qma-mssp-hero solo reseteaba H1. Añadida
                     regla equivalente para H2 (CDU usa H2 como
                     título visible en lugar de H1).
   v1.5  2026-03-13  Fix breadcrumb: elimina margen residual
                     Yoast/Astra en /zdu/ y familia (body class
                     zdu-universe-page). Fusión de regla
                     .zdu-uni__hero-lead duplicada.

   ZDU POSTS INDIVIDUALES â Suprimir breadcrumb Astra nativo
   Scope: body.single-post con URL dentro de /zero-day-unit/
   Problema: body.zdu-universe-page no se aplica a single posts
   (PHP snippet ID 46887 solo actúa en archive/hub de /zdu/).
   CSS no puede filtrar por URL â usamos el selector de Astra
   que incluye el slug del post-parent en body class cuando el
   post pertenece a la categoría ZDU.

   SELECTOR SEGURO: .category-zero-day-unit es la body class
   que WP/Astra inyectan en single posts de esa categoría.
   No afecta otras páginas del blog.
