   6.1 Orbit — sistema solar con planetas y satelites
   ------------------------------------------------------------
   ESTRUCTURA
     .orbit                cuadrado contenedor (aspect-ratio:1).
     .orbit__ring--N       5 anillos decorativos (rotan suaves).
     .orbit__sun           sol central (marca Copernicus).
     .orbit__rail--X       circulo que rota arrastrando un planeta
                           que se ancla en su borde (top:50%; left:0).
     .orbit__planet        marcador en el borde del rail.
     .orbit__planet-inner  pildora con texto. Contra-rota para
                           quedarse horizontal.
     .planet-system        sub-sistema local del planeta. Centrado
                           sobre el planeta. Wrapper en dos capas:
                           __pos (translate al planeta) y __spin
                           (contra-rota la rotacion del rail).
     .satellite-rail       rail interior dentro del planet-system.
                           Cada satelite tiene el suyo.
     .satellite-inner      pildora pequena del satelite, contra-rota
                           respecto al satellite-rail.

   SINCRONIA
     Cada rail principal y su .__inner usan las variables:
       --rail-dur, --rail-dir, --rail-delay
     El .planet-system__spin usa las mismas para anular la rotacion
     heredada del rail.
     Cada satellite-rail y su satellite-inner usan:
       --sat-dur, --sat-dir, --sat-delay
     Mantener identicos los valores en rail e inner evita elipses.
