/* ===================================================
   ISpeedType — Tema inmersivo: RITUAL MALDITO (Halloween)
   Todo va dentro de body.theme-halloween: sin la clase, esto no afecta a nada.
   Estética: cielo morado con luna, cementerio con casa embrujada al fondo,
   niebla que se arrastra, lápidas por tarjetas y velas por letras.

   Reglas de rendimiento (ver notas en styles.css):
     - las capas fijas (cielo, cementerio, niebla) solo animan transform/opacity;
     - las llamas y gotas las gestiona halloween.js con un pool reutilizable;
     - con "reducir movimiento" todo queda estático.
