   mmb-oposiciones.css — Sección "Preparación de Oposiciones"
   ------------------------------------------------------------
   Construido sobre los tokens de mmb-tokens.css (colores, espacios,
   radios, tipografía) → theme-aware y coherente con el resto de la
   plataforma. Solo añade lo específico de oposiciones: chrome de la
   sección (topnav/sidebar), portadas, tarjetas de tema, navegación de
   tema y los BLOQUES VISUALES reutilizables (normativa, importante,
   muy preguntado, actualización legislativa, etc.).
   Enlazar DESPUÉS de mmb-tokens.css + mmb-components.css.
