   SPARK MTG — Hoja de estilo compartida de las páginas de contenido estáticas
   (guías, hub, legales, FAQ, sobre-nosotros, contacto).

   Calca el sistema "ONYX & SLATE" del app React (src/index.css @theme): fondo
   casi negro, texto claro, acento AZUL (#3b82f6) y tipografía Outfit — para que
   el contenido crawlable se vea como el resto de spark-mtg.es. Sustituye a los
   estilos inline morados que cada página duplicaba.
