   --------------------------------------------------------------------------
   CÓMO USARLO: este archivo se carga DESPUÉS de `generator.css` y lo
   sobrescribe por completo (misma especificidad, cascada posterior).
   No cambia ninguna clase ni el HTML/JS generado: solo presentación.

   Paleta "atardecer": el violeta #7c3aed sigue siendo la marca (logo,
   favicon, foco, enlaces). El fucsia y el coral aportan calidez y energía
   en degradados, botones y detalles; el ámbar queda para avisos.
     --lb-violet       #7c3aed  (marca, primario)
     --lb-violet-deep  #6d28d9  (gradientes)
     --lb-violet-ink   #5b21b6  (acentos de texto)
     --lb-fuchsia      #d946ef  (decorativo / texto grande; 3.46:1)
     --lb-fuchsia-deep #a21caf  (texto y botones; 6.32:1 AA)
     --lb-coral        #ff6b5e  (decorativo cálido, sin texto)
     --lb-coral-deep   #e14e42  (iconos/detalles; 3.91:1)
     --lb-pink         #f0abfc  (decorativo, nunca detrás de texto)

     --lb-muted       #5f5870  (texto secundario, AA sobre blanco)
