  Tokens de diseño — fuente de verdad: Manual de estilo HACKEAR.
  Fondos que admite el manual: negro, blanco, turquesa #4FABB2, violeta #9040C8 (y gris claro y azul, secundarios).
  EXCEPCIÓN (decisión de Andrés, 2026-10-17): como el blanco, el turquesa y el violeta cansaban la vista por su contraste,
  las secciones de la portada alternan negro y tres grises muy oscuros (--fondo-1 a --fondo-3). El manual no admite el
  gris oscuro como fondo; se hace igual porque el texto blanco sobre estos grises sigue por encima de 15:1 de contraste
  (lo comprueba una prueba). Rosa y cian quedan como acento: texto, líneas y botones, nunca fondos.

  Tema. El sitio tiene dos modos: NOCHE (el de siempre, el que se ve por defecto) y DÍA (clase `modo-dia` en <html>).
  Todo el CSS usa estos nombres y no el blanco o el negro «a mano»:
    --bg / --text         fondo de la portada (primera sección, encabezado y pie) y color del texto
    --fondo-pagina        fondo de las páginas internas (publicaciones, recursos, contacto): de noche es el negro; de día, el gris

    --on-accent           texto sobre un relleno rosa o cian (siempre oscuro)
    --pink-fg / --cyan-fg el rosa y el cian cuando son TEXTO, línea o borde (de noche son los de marca; de día, versiones
                          oscuras, porque el rosa #ff7ea4 y el cian #7effff sobre fondo claro dan 1,5:1 y 1,0:1)
    --pink / --cyan       los de marca, solo para rellenos (botones, barras)
  El DÍA no es un blanco puro (que encandila): fondos «papel» de luminancia 0,6 a 0,8 (el blanco es 1,0) y texto casi negro.
  Una prueba comprueba el contraste de todas las combinaciones.
