   Se carga después de style.css. Primero redefine los tokens (así todo el
   sitio pasa al tema nuevo), después reemplaza encabezado y portada.

   Paleta: tinta nocturna de fondo, cian solo como luz (líneas, escaneo, foco,
   botón principal), verde solo para estados verificados. Sin emojis, sin
   etiquetas en mayúsculas, sin sombras grises genéricas.
   Tipografías: Chakra Petch (títulos) + IBM Plex Sans (textos y números).
