/* ===================================================
   ISpeedType — Tema inmersivo: ESPACIO PROFUNDO (Viaje estelar)
   Fondo 3D en WebGL (themes/space.js) + interfaz de cabina holográfica.
   Todo va dentro de body.theme-space: sin la clase, esto no afecta a nada.

   Reglas de rendimiento:
     - SIN backdrop-filter: el fondo cambia cada fotograma y el navegador
       tendría que recalcular el desenfoque continuamente;
     - sin text-shadow ni animaciones por letra en el texto principal;
     - los paneles son semitransparentes pero planos (barato de componer).
   =================================================== */
