   Igual que index9 (con sus correcciones) + modo claro/oscuro.
   --panel-dark es un tono fijo (no cambia con el tema): lo usa
   el carrusel, que necesita quedar oscuro en ambos modos para que
   el texto sea legible sobre las fotos. El footer, en cambio, SÍ
   sigue el tema en el MISMO sentido que el header (no invertido):
   claro en modo claro, oscuro en modo oscuro — por eso usa
   --surface-alt/--text y no --panel-dark ni --text solo.
