   Paisaje del genoma — estilos propios de la página.
   Hereda tokens y tipografías de ../styles.css. Los colores del
   dibujo salen de los mismos tokens: landscape.js los lee y arma
   la paleta del SVG, así el paisaje sigue al tema.

   Sin JavaScript la página es un documento normal que explica qué
