   Una sola hoja para las 4 páginas del portal. Reemplaza el
   bloque <style> con el aurora morado que cada página duplicaba.

   Tema: claro/oscuro AUTOMÁTICO según el sistema operativo.
   No hay toggle: los tokens viven en :root y se redefinen en
   @media (prefers-color-scheme: dark). Todo color de la UI sale
   de un token — si algo se ve mal en un tema, se arregla acá.

   Los tokens se declaran como "R G B" (sin rgb()) para que
   Tailwind pueda componer opacidad: rgb(var(--ink) / <alpha-value>).
   Por eso en HTML se usa text-ink/60, bg-surface/80, etc.
