/* ===================================================
   ISpeedType — Tema inmersivo: DEEP WEB (computadora poseída)
   Todo va dentro de body.theme-deepweb: sin la clase, esto no afecta a nada.
   (Los efectos .dw-* los crea themes/deepweb.js solo mientras el tema está activo.)

   Reglas de rendimiento (ver notas en styles.css):
     - nada de text-shadow ni animaciones por letra en el texto principal;
     - la linterna es UNA capa fija con un degradado radial; solo cambian
       3 variables (--dw-x, --dw-y, --dw-r);
     - grano, banda de tracking, destellos y rostros animan solo transform / opacity.

   Seguridad (fotosensibilidad): los destellos de pantalla completa y los rostros solo
   existen en el "modo con sustos" que el usuario elige tras una advertencia. Cada uno
   es un único destello y entre dos hay al menos 1 segundo (nunca más de 3 por segundo).
   En "modo suave" solo hay una sacudida leve y un pulso rojo tenue; con
   prefers-reduced-motion no hay destellos, rostros ni sacudidas.
