/* Pantalla completa: el puente 3D (nave-interior.css/js) es lo único que

   overlays (position:absolute), no empujan/reducen el layout.

   OJO con el z-index acá: este contenedor NO debe tener uno propio (queda
   z-index:auto a propósito). GLAC (#glac-container) es un contenedor FIJO
   global (--z-glac) que necesita aparecer DELANTE del cuarto 3D (paredes/
   piso — si no, la pared opaca lo tapa por completo, bug real encontrado
   por el usuario) pero DETRÁS del tablero de la consola (para que le tape
   las piernas). Como un z-index no puede "partir" a un mismo ancestro en
   dos — todo lo que cuelgue de un ancestro con z-index propio queda
   atado a esa posición como bloque — la solución es NO elevar este
   contenedor entero, sino que CADA pieza de nave-interior.css compita
   directo por su cuenta: `.nave-console` (paredes/piso/GLAC-spot, sin
   z-index) queda detrás de GLAC por defecto, y `.nave-console__front`
   (tablero + anillos, con SU PROPIO z-index alto) queda delante. */
